Synthesis and Application of Innovative and Environmentally Friendly Photocatalysts: A Review

Modern society faces two major challenges: removing pollutants from water and producing energy renewable sources. To do this, science proposes innovative, low-cost, environmentally friendly methods. The heterogeneous photocatalysis process fits perfectly in this scenario. In fact, with photocatalysis, it is possible both to mineralize contaminants that are not easily biodegradable produce hydrogen the splitting reaction or conversion of organic substances present water. However, main challenge field low-cost efficient photocatalysts active under visible light sunlight. objective review compare new proposals for synthesis innovative reflect requirements green chemistry, applied removal production. From comparison, we want bring out strengths weaknesses literature, but above all, ideas improve efficiency guaranteeing principles environmental economic sustainability.
