Research & DevelopmentShenyang Agricultural University researchers used cellulose-derived carbon quantum dots to decorate CdS, nearly doubling visible-light hydrogen production in lab tests. Shenyang Agricultural University has come up with a groundbreaking photocatalyst that turns plant biomass into a powerhouse for hydrogen production. They’ve developed a process that converts cellulose into tiny carbon quantum dots (CQDs) and then attaches them to cadmium sulfide (CdS) nanoparticles. Almost double the hydrogen output when using visible light compared to the unmodified stuff. How Can Cellulose-Derived Carbon Dots Supercharge Clean Hydrogen Production?
