Le développement de sources d'énergie nouvelles, durables et non polluantes est le principal moyen de remédier à la dépendance croissante des sociétés actuelles à l'égard des énergies fossiles, qui entraîne des pénuries d'énergie et des problèmes de pollution de l'environnement.La production photocatalytique d'hydrogène est sans aucun doute le meilleur moyen de résoudre ces problèmes.Le cadre organique Covalent (cofs) est un nouveau type de matériau cristallin poreux relié par une liaison covalente qui présente des avantages tels que la largeur de bande interdite appropriée et une large gamme d 'absorption de lumière visible, et qui est devenu un nouveau PHOTOCATALYSEUR au cours des dernières années.Toutefois, les cofs, en tant que photocatalyseurs, continuent d'être soumis à une combinaison rapide de cavités électro - optiques, ce qui rend difficile la production d'hydrogène souhaitée.Actuellement, on utilise des catalyseurs auxiliaires de métaux précieux tels que Pt pour séparer les électrons photobiologiques des cavités.Les métaux précieux tels que Pt sont coûteux et peu abondants, ce qui rend difficile l'application pratique à grande échelle.
The development of new, sustainable and non-polluting sources of energy is the main way to remedy the growing dependence of today's societies on fossil fuels, which leads to energy shortages and environmental pollution problems. .Photocatalytic production of hydrogen is undoubtedly the best way to solve these problems. The Covalent organic framework (cofs) is a new type of porous crystalline material linked by a covalent bond which has advantages such as the forbidden bandwidth appropriate and a wide range of visible light absorption, and which has become a new PHOTOCATALYST in recent years. However, cofs, as photocatalysts, continue tobe subjected to a rapid combination of electro-optical cavities, which makes it difficult to produce the desired hydrogen. Currently, auxiliary catalysts of precious metals such as Pt are used to separate photobiological electrons from the cavities. Precious metals such as Pt are expensive and scarce, making practical large-scale application difficult.
