Scalable and durable module-sized artificial leaf with a solar-to-hydrogen efficiency over 10%

Here the authors demonstrate a scalable and durable minimodule size artificial leaf with a solar-to-hydrogen efficiency of >10% using a metal-halide perovskite-based photoelectrodes encapsulated with metal foil deposited co-catalysts.

Bias-free solar NH₃ production by perovskite-based photocathode coupled to valorization of glycerol

Photoelectrocatalytic nitrate reduction offers an opportunity for a lower carbon route to ammonia production but has not been realized due to poor efficiency. Here an efficient modified lead halide perovskite photocathode is coupled to glycerol oxidation anode resulting in a bias-free photocurrent density greater than 20 mA cm⁻².

All-perovskite-based unassisted photoelectrochemical water splitting system for efficient, stable and scalable solar hydrogen production

Ideal photoelectrochemical systems for hydrogen production should be highly efficient, stable and scalable. Here the authors report that a perovskite-based system with promising efficiency and stability can be scaled to cells of several square centimetres in area as well as formed into mini-modules with overall area >100 cm².

Bias-free solar hydrogen production at 19.8 mA cm⁻² using perovskite photocathode and lignocellulosic biomass

While light-driven water splitting offers a means to produce renewable H₂ fuel, water oxidation limits performances and yields low-value products. Here, authors demonstrate a photoelectrochemical cell that converts lignocellulosic biomass into valuable products alongside H₂.

Unassisted selective solar hydrogen peroxide production by an oxidised buckypaper-integrated perovskite photocathode

It is of high demand yet challenging to boost the efficiency of solar driven hydrogen peroxide synthesis. Herein, the authors intergrade perovskite-based photocathode and oxidised buckypaper for unassisted solar H2O2 production with a solar-to-chemical conversion efficiency of ~1.463 %.

Direct propylene epoxidation with oxygen using a photo-electro-heterogeneous catalytic system

Aerobic oxidation of propylene is a potential green route to propylene oxide production without the need for harmful oxidizing or wasteful sacrificial reagents. Here, a proof-of-concept integrated photo-electro-heterogeneous catalytic system performs this reaction using in situ-generated H₂O₂.
