Green Photocatalysts for Energy and Environmental Process

Abstract

Energy and environmental crisis are two major challenges in present-day life. The advent usage of fossil fuels for electricity and transportation had resulted in global warming with deadly repercussions. Photocatalysis could be a good alternative to solve the present-day problems. Engineering the material for maximum solar irradiation harvesting, efficient charge generation, its transport to reaction centers, and high catalytic properties are the main priorities; in this sense, two-dimensional materials could be suitable for photocatalysis because of its physical, electrical, and chemical properties and the possibility to chemically tailor them. Photoinduced charge carriers could catalyze various chemical reactions for crucial applications. Hydrogen fuel could be used for hydrogen fuel cell to generate the electricity and power the electric vehicles. Major greenhouse gas, such as CO2 emitted by various industries and conventional automobiles, could be reduced to high-energy fuel such as methanol, ethanol, or formate. Photodegradation could decompose toxic organic substances from water-polluted sources. Human effort and expenditures could be saved by self-cleaning photocatalysis in offices, hospitals, or photovoltaic panels. Photocatalytic materials may play a critical role in effective cancer therapy for its sensitizing property and ability to produce reactive oxygen species which kills cancer.
