Unveiling actual role of metal cocatalysts

Synchronizing periodic excitations of photocatalysts with a Michelson interferometer on operando FT-IR spectroscopy, researchers succeeded in observing and identifying the reactive electron species for photocatalytic hydrogen evolution. In contrast to the traditional belief, this study demonstrates that not the free electrons in metal cocatalysts but the electrons trapped in the periphery of cocatalysts directly contribute

New process vaporizes plastic bags and bottles, yielding gases to make new, recycled plastics

Chemists have developed a catalytic process that turns the largest component of today’s plastic waste stream, polyolefin plastic bags and bottles, into gases — propylene and isobutylene — that are the building blocks of polypropylene and other types of plastics. The process uses inexpensive solid catalysts that can be scaled to industrial production, making this
