Environment Friendly g-C3N4-Based Catalysts and Their Recent Strategy in Organic Transformations

Abstract

Organic molecules synthesized in an environmentally friendly manner have excellent therapeutic potential. The entire preparation technique was examined in the existence of a light source, implying that light has been replaced by heating and the usage of dangerous chemicals has decreased, resulting in less pollution of the environment. The advantages of these nanocarbon catalysts include high efficiency, environmentally friendly synthesis, eco-friendly, inexpensive, and non-corrodible. In organic transformations, solid metal base/metal-free catalysts produce better results. Here, the metal-free semiconductor g-C3N4 was used to demonstrate the catalytic behavior of organic conversions. g-C3N4 is a two-dimensional material and a p‑type semiconductor to enhance the photocatalytic activity. The excellent properties of g-C3N4 sheet lead to the support of metals to form metal-organic frameworks. Most of the reactions gained positive response under visible light irradiation. This review will inspire readers in widen the applications of g-C3N4 based catalyst in various organic transformation reactions.
