Abstract

Toluene is an aromatic pollutant that can be widely found in many industries. Due to its toxicity, its total decomposition has been investigated by many researchers using various ways. One alternative way is the usage of catalyst and light to decompose toluene. However, so far, it is still remained as a challenge. On the other hand, the need to use cheap, abundant, and safe sources to prevent our sustainability makes the utilization of solar energy one of the ideal solutions for our problems. As visible light is the main part of our solar energy, the development of photocatalysts that able to work under visible light irradiation is highly required. One of the efforts to realize it is by designing materials that able to absorb visible light especially that of longer wavelength, such as up to 600 nm. A red color-material, Tantalum (V) nitride (Ta3N5) is one such potential photocatalyst. Its photocatalytic activity was discovered for water splitting reaction under visible light irradiation [1]. Recent progress reported that Ta3N5 nanoparticles showed higher activity than the bulk Ta3N5 for hydrogen evolution [2] and methylene blue degradation [3].
可见光照射下氮化钽纳米颗粒对甲苯分解活性的增强
甲苯是一种芳香性污染物,广泛存在于许多工业中。由于它的毒性,许多研究者用各种方法研究了它的总分解。另一种方法是使用催化剂和光来分解甲苯。然而,到目前为止,它仍然是一个挑战。另一方面,为了防止我们的可持续发展,需要使用廉价、丰富和安全的资源,这使得利用太阳能成为解决我们问题的理想方案之一。由于可见光是太阳能的主要组成部分,因此迫切需要开发能够在可见光照射下工作的光催化剂。实现这一目标的努力之一是设计能够吸收可见光的材料,特别是波长较长的可见光,如高达600纳米的可见光。一种红色材料,氮化钽(V) (Ta3N5)就是这样一种潜在的光催化剂。在可见光照射下发现了其光催化裂解反应的活性。近年来的研究进展表明,纳米Ta3N5在析氢[2]和亚甲基蓝降解[3]方面表现出比体Ta3N5更高的活性。
