Metal and non-metal oxide-supported selenium as potential industrial catalysts

Selenium-based catalysts have emerged as promising tools for industrial application due to their environmentally-friendly features. In the past decade, people have reported a wide variety of selenium-based catalysts, such as organoselenium catalysts, polymer-supported selenium catalysts, carbon-supported selenium catalysts, and metal or non-metal oxide-supported selenium catalysts. These catalysts have been extensively applied in numerous reactions of practical importance. Notably, metal or non-metal oxide-supported inorganic selenium catalysts hold great promise for industrial use owing to the low cost and durability of their supports. This paper aims to comprehensively review the current progress and give a perspective.
