Solar Water Splitting: A Raman Field Guide
How Raman and Raman mapping verify BiVO4 photoanodes, solar-fuel photoelectrodes, and photocatalytic water treatment across ProTrusTech-featured research.
A Solvent Swap Lifts a Photoanode’s Output 15-Fold — Raman Shows Why
Swapping in an ethylene-glycol/water solvent yields pure monoclinic BiVO4 films — 15× the photocurrent for water splitting, with 2D Raman mapping as proof.
One Nanowire Array, Two Jobs: Destroy the Pollutant, Then Detect It
Two studies, one idea: semiconductor nanowire arrays that photocatalytically destroy a dye and, decorated with silver, detect it by SERS down to 10⁻⁹ M.
A BiVO4 Photoanode Turns a Biodiesel Waste Stream Into Hydrogen Fuel and a $150/kg Chemical
A biodiesel by-product becomes a photoanode’s favorite fuel — hydrogen at the cathode, valuable dihydroxyacetone and formic acid at the anode.
One Solvent Swap Builds a More Durable Water-Splitting Catalyst
Swapping water for a deep eutectic solvent fixes a longstanding alloy-plating problem — and builds a catalyst that runs 10+ hours without fading.
One Anion Swap Turns Copper Oxide Into a Better Solar Water-Splitting Co-Catalyst
Nitrate or sulfate — a choice built into a single plating bath — decides whether copper oxide becomes a porous powerhouse or a dense underperformer.
