The storage of renewable energy is crucial for the substitution of fossil fuels with renewable energy. Hydrogen is the first step in the conversion of electricity from renewable sources to an energy carrier. However, hydrogen is technically and economicall ...

The single-layer graphene film, when incorporated with molecular-sized pores, is predicted to be the ultimate membrane. However, the major bottlenecks have been the crack-free transfer of large-area graphene on a porous support, and the incorporation of mo ...

The potential applications of graphene-based materials in catalysis have been intensively studied owing to the unique 2D structure of graphene and its superior physicochemical properties. Recently, graphene-coated oxide composites have been fabricated and ...

The electrochemical reduction of CO2 (CO2RR) into valuable products represents a step towards alleviating global warming and the energy crisis. However, the sluggish kinetics of the CO2RR and the competitive hydrogen evolution reaction (HER) still limit th ...

Carbide-supported metal catalysts attract extensive research interests owing to the special properties of metal carbide and the interactions between metals and the carbide supports. While surface oxide species are inevitable in carbide materials, their rol ...

Organic-inorganic metal-halide perovskite solar cells (PSCs) have achieved a certified power-conversion efficiency (PCE) of 25.5%. However, long-term stability and air stability of the PSCs are still major concerns and hamper commercialization. Herein, we ...

CO-selective metals (e.g., Ag) on Cu catalysts improve the selec-tivity of multi-carbon (C2+) products in electrochemical CO2 reduc-tion. However, the origin of the improvement remains unclear due to the convolution of tandem and interface effects. Here, A ...

The electrochemical reduction of carbon dioxide (CO2RR) has attracted enormous interest because of the energy crisis and climate change; however, more efficient catalysts are required for practical applications. Herein, we present electrospinning as a faci ...

We report the use of two earth abundant molybdenum sulfide-based cocatalysts, Mo(3)S(13)(2-)clusters and 1T-MoS2 nanoparticles (NPs), in combination with the visible-light active metal-organic framework (MOF) MIL-125-NH2 for the photocatalytic generation o ...

The electrochemical conversion of CO 2 into acetaldehyde offers a sustainable and green alternative to the Wacker process. However, current electrocatalysts cannot effectively compete with heterogeneous processes owing to their limited selectivity towards ...
