Efficient Alkaline Hydrogen Evolution Electrocatalyst
January 4, 2021Researchers realized a NiCo(OH)x-CoyW catalyst with a bush-like heterostructure via gas-template-assisted electrodeposition, followed by an electrochemical etching-growth process, which ensured a high active area and fast gas release kinetics for a superior hydrogen evolution reaction.
Nanocarbon Enhanced 2D Photoelectrodes For Oxygen/Hydrogen Evolution Reactions
July 28, 2020 Researchers examined various 2D layered photoanodes/photocathodes, including graphitic carbon nitrides, transition metal dichalcogenides, layered double hydroxides, layered bismuth oxyhalide nanosheets, and MXenes, combined with advanced nanocarbons (carbon dots, carbon nanotubes, graphene, and graphdiyne) as co-catalysts to assemble integrated photoelectrodes for oxygen/hydrogen evolution reactions.
Boron Nanosheet-Supported Rh Catalysts for Hydrogen Evolution Reaction (HER)
April 27, 2021 Researchers designed an outstanding HER electrocatalyst, highly dispersed rhodium (Rh) nanoparticles with an average diameter of only 3 nm supported on boron (B) nanosheets. The HER catalytic activity is even comparable to that of commercial platinum catalysts.
Enhanced Water Electrolysis Activity at High Current Density
November 25, 2020 Researchers prepared an N-doped graphene-decorated NiCo alloy coupled with mesoporous NiCoMoO nano-sheet grown on 3D nickel foam (NiCo@C-NiCoMoO/NF) for water splitting.
Ruthenium-Based Electrocatalysts for Effective Hydrogen Evolution Reaction
April 27, 2021 Researchers summarized four main strategies for improving the hydrogen evolution reaction (HER) performance of Ru-based catalysts.
Low-cost Electrocatalyst for Hydrogen Evolution Reaction (HER)
August 13, 2021 Using first-principles calculations, researchers designed a defect and N-, S-, P-doped penta-graphene (PG) as a two-dimensional (2D) electrocatalyst for HER. Its stability, electronic properties and catalytic performance were investigated.
COP 26
October 12, 2021 In just a few days the nations of the world will once again meet to discuss climate change. The meeting will likely set the stage for action –or lack thereof- that will make or break our collective effort to halt the dumping of greenhouse gases in the … Continue reading
Trillion-Dollar Infrastructure Bill
BackgroundThe Senate recently approved a bipartisan 1-trillion infrastructure bill that earmarked 8.3 billion for water projects in the drought-stricken West. Assuming the House concurs and the President signs it into law, the bill will appropriate 1.15 billion for improving water storage, transport infrastructure and projects to replenish aquifers, 1 billion … Continue reading
Size Of The Canal
The length of a canal from the Pacific to Death Valley would be about 200 miles, similar to the Turkish Straits -from the southern end of the Dardanelles to the northern end of the Bosporus. The Black Sea is 56.2 times larger (168,500 sq mi) and 25.7 times deeper (7,257 ft) than Death Valley; due … Continue reading
