Continuous flow photosynthesis of methanol from methane by plasmonic charge accumulation - Nature Communications
Abstract Direct oxidation of methane (CH4) to methanol (CH3OH) typically requires elevated temperatures and pressures, making it challenging to achieve high yield and selectivity under mild conditions. Here, we show a surface plasmon-mediated catalyst designing strategy based on the synergy between Pd nanoparticles and ZnO nanosheets.

Zeolite-confined Cu single-atom clusters stably catalyse CO to acetate at 1 A cm−2 beyond 1,000 h - Nature Nanotechnology
Abstract The electrochemical CO reduction reaction (CORR) has attracted a surge of research interest in sustainably producing high-value multi-carbon products, such as acetate. Nevertheless, most current CORR catalysts exhibit low acetate current densities, poor longevity and limited acetate selectivity.

An oxide-promoted, self-supported Ni4Mo catalyst for high current density anion exchange membrane water electrolysis
An oxide-promoted, self-supported Ni4Mo catalyst for high current density anion exchange membrane water electrolysis† Anionic exchange membrane (AEM) water electrolyzers are emerging as a cost-effective technology for green hydrogen production. However, state-of-the-art AEM electrolyzers rely on platinum group metal (PGM) catalysts for the hydrogen evolution reaction (HER).

Di-piperidinium-crosslinked poly(fluorenyl-co-terphenyl piperidinium)s for high-performance alkaline exchange membrane fuel cells
Di-piperidinium-crosslinked poly(fluorenyl-co-terphenyl piperidinium)s for high-performance alkaline exchange membrane fuel cells† Modern anion exchange membrane (AEM) fuel cells (AEMFCs) call for highly conductive, durable, and mechanically tough AEMs and ionomers.
Branched Poly(Aryl Piperidinium) Membranes for Anion‐Exchange Membrane Fuel Cells
Abstract High-molecular-weight branched poly(aryl piperidinium) membranes with high conductivity (147 mS cm−1 at 80 °C) and excellent mechanical (26 % swelling ratio) and chemical stability have been prepared. Anion-exchange membrane fuel cells (AEMFCs) using these membranes exhibit high peak power density (2.3 W cm−2) and durability (500 h). Abstract Anion-exchange membrane fuel cells (AEMFCs) are a promising, next-generation fuel cell technology.
High-performance anion exchange membrane water electrolyzers with a current density of 7.68 A cm−2 and a durability of 1000 hours
High-performance anion exchange membrane water electrolyzers with a current density of 7.68 A cm−2 and a durability of 1000 hours† Low-cost anion exchange membrane (AEM) water electrolyzers (AEMWEs) are a new technology for the production of high-purity hydrogen; however, their current density and durability are far lower than those of proton exchange membrane water electrolyzers (PEMWEs).
