Methane is the main component of natural gas and shale gas. It chemically stable, its activation often requires high temperatures, which lead to extensive transformation into undesirable products such as CO CO2. Thus, development efficient catalysts for selective methane represents a substantial challenge. In this work, we synthesized La2O2CO3 samples with different morphologies (rod- plate-shapes) at nanometer scale. We observed that one rod-shaped exhibited best catalytic properties among...
We present a facile synthetic method that yields Ag@CoxP core–shell-type heterogeneous nanostructures with excellent oxygen evolution reaction (OER) activity. This nanocatalyst can deliver current density of 10 mA/cm2 at small overpotential 310 mV and exhibits high catalytic stability. Additionally, the activity is 8 times higher than Co2P nanoparticles, owing primarily to strong electronic interaction between Ag core CoxP shell.
Among the electrolyzers under development for CO2 electroreduction at practical reaction rates, gas-fed approaches that use gas diffusion electrodes (GDEs) as cathodes are most promising. However, insufficient long-term stability of these technologies precludes their commercial deployment. The structural deterioration catalyst material is one possible source device durability issues. Unfortunately, this issue has been insufficiently studied in systems using actual technical electrodes....
The advantage of employing gas diffusion electrodes (GDEs) in carbon dioxide reduction electrolyzers is that they allow CO2 to reach the catalyst gaseous state, enabling current densities are orders magnitude larger than what achievable standard H-type cells. gain reaction rate comes, however, at cost stability issues related flooding occurs when excess electrolyte permeates micropores GDE, effectively blocking access catalyst. For operated with alkaline electrolytes, leaves clear traces...
The most promising strategy to scale up the electrochemical CO2 reduction reaction (ec-CO2RR) is based on use of gas diffusion electrodes (GDEs) that allow current densities close range 1 A/cm2 be reached. At such high densities, however, flooding GDE cathode often observed in electrolysers. Flooding hinders access catalyst, and by thus leaving space for (unwanted) hydrogen evolution, it usually leads a decrease observable Faradaic efficiency products. To avoid as much possible has become...
Abstract The fluid‐filled cystic cavity sealed by a dense scar developed following traumatic spinal cord injury (SCI) has been major obstacle to neural regeneration and functional recovery. Here the transected lesion is bridged using self‐assembling peptide (F‐SAP) hydrogel loaded with membrane‐permeable intracellular sigma (ISP) LAR (ILP), targeted at perturbing chondroitin sulfate proteoglycan (CSPG) inhibitory signaling. As compared F‐SAP chondroitinase ABC, F‐SAP+ISP/ILP promotes...
Titanium dioxide is widely used in sunscreens because of its strong ultraviolet (UV) light absorbing capabilities and resistance to discoloration under UV exposure. However, when deposited as a thin film, the high refractive index titanium typically results whiteness opacity, which limits use for material surfaces, long-term natural appearance relevance. Since whitish due scattering reflection on interface oxide particles air, one can increase transparency TiO2 coatings by forming continuous...
We study the role of binders (ionomers) in determining life-span gas diffusion electrodes (GDEs) used for high throughput CO2-to-CO electrolysis. compare two typical ionomer materials (Nafion and Fumion, both are widely preparation Ag nanoparticles-based catalyst inks) to show that when zero-gap membrane/electrode assemblies, Fumion-containing inks superior Nafion-based ones can uphold a very CO-selectivity electrochemical CO2 reduction reaction longer time. This is due ability Fumion...
After complete transection of the thoracic spinal segment, neonatal rats exhibit spontaneous locomotor recovery hindlimbs, but this is not found in adult after similar injury. The potential mechanism related to difference and remains unknown. In study, 342 animals were analyzed. vascular endothelial growth factor (VEGF) level segments below injury sites was significantly higher postnatal day 1 (P1) compared with 28-day-old (P28) following a T9 transection. VEGF administration P28 improved...
Colloidal electrocatalysts are commonly synthesized using organic capping agents (surfactants), which control the size distribution and shape of resulting nano-objects prevent them from agglomerating during after synthesis. However, presence a surfactant shell on catalyst is detrimental, as performance electrocatalyst depends crucially ability reactants to access active surface sites. Techniques for postsynthesis deprotection therefore mandatory removing otherwise blocked reactions sites...
The direct conversion of syngas to ethanol is a promising route for the sustainable production value-added chemicals and fuels. While Fe-promoted Rh-based catalysts have long been studied because their notable activity selectivity towards ethanol, nature Rh-Fe interaction catalyst structure under reaction conditions remain poorly understood due intrinsic complexity heterogeneous prepared by conventional approaches. In this work, we construct well-defined RhFe@SiO2 model via surface...

In this work, we discuss the application of a gas diffusion electrode (GDE) setup for benchmarking electrocatalysts reductive conversion CO2 (CO2RR: reduction reaction). Applying silver nanowire (Ag-NW) based catalyst, it is demonstrated that in GDE conditions can be reached, which are relevant industrial to CO. This reaction part so-called 'Rheticus' process uses CO subsequent production butanol and hexanol on fermentation approach. contrast conventional half-cell measurements using liquid...
Abstract The partial oxidation of methane is a promising method for the efficient production syngas. To implement this process using common stainless steel reactors, an inexpensive catalyst that functions at 650 °C or below necessary. However, base metal catalysts typically require much higher temperatures, and they are deactivated by re-oxidation coke formation. Here we report modification zeolite-supported 3 wt% cobalt with trace amount mono-atomically dispersed rhodium (0.005 wt%)...
Molecular hybrid catalysts, such as cobalt(II) phthalocyanine (CoPc) complexes anchored to multi-walled carbon nanotubes (MWCNTs), provide selective CO2 conversion toward CO with high current densities, exceeding 0.1 A cm−2 in microfluidic or zero-gap (membrane) electrolyzers. However, the practicality of electroreduction is essentially determined by catalyst stability against mechanical and (electro)chemical degradation. Here, we report a new mechanism for observable degradation [email...
Rh sub-nano clusters supported on zeolite are remarkably more active, selective, and durable than nanoparticles for the conversion of methane to syngas at low temperature.
