Replacing the sluggish oxygen evolution reaction (OER) with hydrazine oxidation reaction (HzOR) has been proved to be an efficient approach to increase the hydrogen production efficiency through water electrolysis. Herein,...
Water splitting by electricity is believed to be a promising approach to obtain high-purity H2 on a large scale. Highly efficient electrocatalysts are of great importance for the electrocatalytic hydrogen...
In the GeO2/nanocable, amorphous carbon and graphene spontaneously construct a nanocable structure, graphene “core” promises the good electrical conductivity while the amorphous carbon “shell” guarantees the fast Li ions diffusion.
Adding
a cocatalyst to a semiconductor catalyst is often considered
an effective measure to increase the efficiency of the photocatalytic
hydrogen evolution reaction. Nowadays, noble metals are the state-of-the-art
cocatalysts for the hydrogen evolution reaction. Due to their high
cost and scarcity, it is imperative to develop cocatalysts prepared
from cheap and abundant elements. Here, RuSe2 was used
as an effective substitute for precious metal promoters such as Pt
to enhance the efficiency of g-C3N4 for the
hydrogen evolution reaction. A high efficiency of 13417.3 μmol·g–1·h–1 was obtained. It was 214
times higher than that of g-C3N4 and 2.8 times
higher than that of 3%Pt/g-C3N4. Density functional
theory calculations were performed. The (210) and (200) crystal faces
of RuSe2 showed lower ΔG
H* than Pt(111), indicating higher hydrogen evolution efficiency. Compared
with the Pt cocatalyst, metallic RuSe2 cocatalysts exhibited
superior performance. Meanwhile, the electrocatalytic activity was
also investigated in an alkaline medium. It showed a decent electrocatalytic
activity and high stability. These findings might provide a prototype
to develop cheap and efficient cocatalysts for large-scale water splitting.
Metal-organic frameworks (MOFs) derivatives are among the most promising catalysts for hydrogen evolution reaction (HER) for clean hydrogen energy production. Herein, we report the in-situ synthesized MOFs-derived CoPO hollow polyhedron...
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
