Catalytic combustion of methane is a promising way eliminating fugitive emissions to meet the rising requirement wide application natural gas vehicles. The performance catalysts for has been found be significantly affected by variety lattice defects, oxygen vacancies, and metal–support interactions which are connected with category, morphology, crystal type both active components supports. Choices additives preparation methods also play important roles in catalytic methane. In this Review,...
Abstract Developing acid‐stable electrocatalysts with high activity for the oxygen evolution reaction (OER) is of paramount importance many energy‐related technologies. This work reports that ultrathin nitrogen‐doped carbon coated oxygen‐vacancy (Vo·) rich RuO 2 nanoparticles on nanotubes (CNTs) (NC@Vo·‐RuO /CNTs‐350), synthesized through controlled calcination in air, an efficient electrocatalyst OER.

H2 generation under sunlight offers great potential for a sustainable fuel production system. To achieve high efficiency solar-to-hydrogen conversion, multijunction photoelectrodes have been commonly employed to absorb large portion of the solar spectrum and provide energetic charge carriers water splitting. However, design performance such tandem devices has fundamentally limited by current matching between various absorbing layers. Here, exploiting lateral carrier extraction scheme...

Self-organized AlGaN nanowires by molecular beam epitaxy have attracted significant attention for deep ultraviolet optoelectronics. However, due to the strong compositional modulations under conventional nitrogen rich growth conditions, emission wavelengths less than 250 nm remained inaccessible.
