PubChem (https://pubchem.ncbi.nlm.nih.gov) is a public repository for information on chemical substances and their biological activities, launched in 2004 as component of the Molecular Libraries Roadmap Initiatives US National Institutes Health (NIH). For past 11 years, has grown to sizable system, serving resource scientific research community. consists three inter-linked databases, Substance, Compound BioAssay. The Substance database contains deposited by individual data contributors...
Atomically dispersed noble metal catalysts often exhibit high catalytic performances, but the loading density must be kept low (usually below 0.5%) to avoid formation of nanoparticles through sintering. We report a photochemical strategy fabricate stable atomically palladium-titanium oxide catalyst (Pd1/TiO2) on ethylene glycolate (EG)-stabilized ultrathin TiO2 nanosheets containing Pd up 1.5%. The Pd1/TiO2 exhibited activity in hydrogenation C=C bonds, exceeding that surface atoms...
Improving Reactions at Interfaces Alloying precious metals such as platinum with more abundant transition metals, iron and nickel, can both improve their catalytic reactivity lower catalyst cost. Chen et al. (p. 495 ) explored using coatings of oxide–hydroxide layers on supported nanoparticles for CO oxidation. The presence this layer allowed the reaction to run rapidly room temperature by bringing together different sites two metals. addition nickel improved lifetime, an oxidative...
Surface coordination chemistry of nanomaterials deals with the on how ligands are coordinated their surface metal atoms and influence properties at molecular level. This Perspective demonstrates that there is a strong link between shape-controlled synthesis, many intriguing nanomaterials. While small adsorbates introduced in synthesis can control shapes nanocrystals by minimizing energy via preferential specific facets, properly nanoparticles readily promote catalysis steric interactions...
Abstract Crystal phase regulations may endow materials with enhanced or new functionalities. However, syntheses of noble metal-based allomorphic nanomaterials are extremely difficult, and only a few successful examples have been found. Herein, we report the discovery hexagonal close-packed Pt–Ni alloy, despite fact that alloys typically crystallized in face-centred cubic structures. The alloy nano-multipods synthesized via facile one-pot solvothermal route, where branches take shape...
Abstract Atomically dispersing metal atoms on supports provides an ideal strategy for maximizing utilization catalysis, which is particularly important fabricating cost‐effective catalysts based Earth‐scarce metals. However, due to the high surface energy and thus instability of single atoms, it remains challenging fabricate stable atomically dispersed catalysts. Here, strategies stabilizing various are summarized. Based enhance interaction between support prevent sintering several...
Sulfur and polysulfides play important roles on the environment energy storage systems, especially in recent hot area of high density lithium–sulfur (Li–S) batteries. However, further development Li–S battery is still retarded by lack complete mechanistic understanding sulfur redox process. Herein we introduce a conductive Lewis base matrix which has ability to enhance performance battery, via complicated chemistry electrolyte/carbon interface combined operando Raman spectroscopy functional...
More Greasy, more selective: amine-capped Pt(3)Co nanocatalysts were synthesized and used for the hydrogenation of cinnamaldehyde (CAL). Capping catalysts with amines that contain long carbon chains results in an ordered surface "array", which high selectivity towards C=O can be achieved because C=C bond CAL does not interact surface. The longer amine, higher selectivity.
Air-stable atomically thick copper nanosheets are prepared and used for selective electrochemical reduction of CO 2 into CO.
Surface molecular information acquired in situ from a catalytic process can greatly promote the rational design of highly efficient catalysts by revealing structure-activity relationships and reaction mechanisms. Raman spectroscopy provide this rich structural information, but normal is not sensitive enough to detect trace active species adsorbed on surface catalysts. Here we develop general method for monitoring heterogeneous processes through shell-isolated nanoparticle-enhanced (SHINERS)...
Abstract Metal-support interaction is one of the most important parameters in controlling catalysis supported metal catalysts. Silica, a widely used oxide support, has been rarely reported as an effective support to create active metal-support interfaces for promoting catalysis. In this work, by coating Cu microparticles with mesoporous SiO 2 , we discover that Cu/SiO interface creates exceptional effect promote catalytic hydrogenation esters. Both computational and experimental studies...
Atomically dispersed supported metal catalysts are drawing wide attention because of the opportunities they offer for new catalytic properties combined with efficient use metals. We extend this class materials to that incorporate atomically atoms as promoters. The used challenging nitroarene hydrogenation and found have both high activity selectivity. promoters single-site Sn on TiO2 supports nanoparticle catalysts. Represented M/Sn-TiO2 (M = Au, Ru, Pt, Ni), these decidedly outperform...
Developing earth-abundant and low-cost electrocatalysts for water splitting is important the conversion systems of renewable clean energy. Herein, under guidance theoretical calculations, a new type skutterudite-type ternary cobalt nickel phosphide (Co1–xNixP3) nanoneedle arrays (NAs) fabricated on carbon cloth water. The electronic structure was tuned by doping an appropriate amount Ni, resultant Co0.93Ni0.07P3 displayed good catalytic activity toward hydrogen evolution reaction (HER) with...
Maintaining the stability of single-atom catalysts in high-temperature reactions remains extremely challenging because migration metal atoms under these conditions. We present a strategy for designing stable by harnessing second to anchor noble atom inside zeolite channels. A rhodium-indium cluster catalyst is formed silicalite-1 through situ indium during alkane dehydrogenation. This demonstrates exceptional against coke formation 5500 hours continuous pure propane dehydrogenation with 99%...
Spontaneous migration of atomic hydrogen species from metal particles to the surface their support, known as spillover, has been claimed play a major role in catalytic processes involving hydrogen. While this phenomenon is well established on reducible oxide supports, its realization much more commonly used non-reducible oxides still challenged. Here we present general strategy enable effective spillover over SiO2 with aid gaseous organic molecules containing carbonyl group. By using...
CO poisoning of Pt-group metal catalysts is a long-standing problem, particularly for hydrogen oxidation reaction in proton exchange membrane fuel cells. Here, we report catalyst Ru oxide-coated supported on TiO2 (Ru@RuO2/TiO2), which can tolerate 1-3% CO, enhanced by about 2 orders magnitude over the classic PtRu/C catalyst, electrooxidation rotating disk electrode test. This work stably 1% CO/H2 50 h. About 20% active sites survive even pure environment. The high tolerance not via...
Composite oxides have been widely applied in the hydrogenation of CO/CO2 to methanol or as component bifunctional oxide–zeolite for synthesis hydrocarbon chemicals. However, it is still challenging disentangle stepwise formation mechanism CH3OH at working conditions and selectively convert CO2 chemicals with narrow distribution. Here, we investigate reaction network over a series spinel (AB2O4), among which Zn-based nanostructures offer superior performance synthesis. Through (quasi) situ...
