Chemical industry is a stubborn sector for decarbonization but the benefits could be enormous. To cut the emission of chemical industry, current solution is electrification of which the power is supplied by grid electricity, while the long-term goal is to develop pure renewable energy-driven carbon-neutral or carbon-negative techniques. To this regard, photocatalysis is among the most appealing pathways. In a recent study in ACS Energy Letter, the economic viability of photocatalytic chemical production is found to be promoted by reduced cost of renewable energy and enhanced efficiency of LED.
