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...
Plasmonic metal/semiconductor heterostructures show promise for visible-light-driven photocatalysis. Gold nanorods (AuNRs) semi-coated with TiO2 are expected to be ideally structured systems hydrogen evolution. Synthesizing such structures by wet-chemistry methods, however, has proved challenging. Here we report the bottom-up synthesis of AuNR/TiO2 nanodumbbells (NDs) spatially separated Au/TiO2 regions, whose governed NRs' diameter, and higher curvature lower density CnTAB surfactant at...

The power conversion efficiency of perovskite solar cells (PSCs) has ascended from 3.8% to 22.1% in recent years. ZnO been well-documented as an excellent electron-transport material. However, the poor chemical compatibility between and organo-metal halide makes it highly challenging obtain efficient stable PSCs using layer.

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.

Electrochemical conversion of CO2 into fuels using electricity generated from renewable sources helps to create an artificial carbon cycle. However, the low efficiency and poor stability hinder practical use most conventional electrocatalysts. In this work, a 2D hierarchical Pd/SnO2 structure, ultrathin Pd nanosheets partially capped by SnO2 nanoparticles, is designed enable multi-electron transfer for selective electroreduction CH3 OH. Such structure design not only enhances adsorption on ,...
Air-stable atomically thick copper nanosheets are prepared and used for selective electrochemical reduction of CO 2 into CO.
Perovskite solar cells (PSCs) have reached certified efficiencies of up to 23.7% but suffered from frailness and instability when exposed ambient atmosphere. Zinc oxide (ZnO), used as electron transport layer (ETL) on PSCs, gives rise excellent electronic, optic, photonic properties, yet the Lewis basic nature ZnO surface leads deprotonation perovskite layer, resulting in serious degradation PSCs using ETL. Here, we report a simple effective strategy convert into ZnS at ZnO/perovskite...
Owing to the ionic nature of lead halide perovskites, their halide-terminated surface is unstable under light-, thermal-, moisture-, or electric-field-driven stresses, resulting in formation unfavorable defects. As a result, nonradiative recombination generally occurs on perovskite films and deteriorates efficiency, stability, hysteresis performances solar cells (PSCs). Here, iodide management strategy was developed through use cesium sulfonate stabilize surface. It found that pristine...
Research on solvent chemistry, particularly for halide perovskite intermediates, has been advancing the development of solar cells (PSCs) toward commercial applications. A predictive understanding effects formation is thus essential. This work systematically discloses relationship among basicity solvents, solvent-contained intermediate structures, and intermediate-to-perovskite α-FAPbI3 evolutions. Depending their basicity, solvents exhibit own favorite bonding selection with FA+ or Pb2+...
In many previous studies, nonaqueous synthesis of Pt nanocubes with tunable size has been achieved by the use metal carbonyls (e.g., Fe(CO)5, Co2(CO)8, W(CO)6). The presence zero-valent metals in was demonstrated as key factor to nanocube formation but role CO entirely ignored. By using alone, we have now that favorable growth is mainly owing effect (100) surface stabilized co-adsorption and amine.
