Abstract

Recently, TiO2 nanotube arrays (TNTAs) have attracted researcher’s attention in the fields of energy production and environmental remediation applications; this is mainly due to their unique optoelectronic characteristics, corrosion resistance, chemical and mechanical stability. In this study, the ability of employing of TiO2 nanotube arrays-based catalysts in the field of photocatalytic CO2 reduction has been investigated. Possible modification strategies have been presented for improving the TNTAs performance by using different types of nanomaterials including graphitic carbon nitrides (g-C3N4), metal-organic frame work (MOF), reduced graphene oxide (RGO) and gold nanoparticles (Au NPs). The TNTAs composites were characterized using XRD and FESEM analyses and the results revealed the successful synthesis of these composites. The TNTAs and their composites exhibited good results for the photo-conversion of CO2 into CH4 gas product. This study gives new ideas for making and developing low-cost Ti metal-based nanomaterials which can be used in the future for recycling the CO2 gas emissions into useful solar fuels.

将改性二氧化钛纳米管阵列作为高效光催化剂纳米材料用于能源和环境应用

最近，二氧化钛纳米管阵列（TNTAs）在能源生产和环境修复应用领域引起了研究人员的关注，这主要是由于其独特的光电特性、耐腐蚀性、化学和机械稳定性。本研究调查了基于 TiO2 纳米管阵列的催化剂在光催化还原二氧化碳领域的应用能力。通过使用不同类型的纳米材料，包括石墨碳氮化物（g-C3N4）、金属有机框架（MOF）、还原氧化石墨烯（RGO）和金纳米颗粒（Au NPs），提出了提高 TNTAs 性能的可能改性策略。利用 XRD 和 FESEM 分析对 TNTAs 复合材料进行了表征，结果表明这些复合材料的合成是成功的。TNTAs 及其复合材料在将 CO2 光转化为 CH4 气体产物方面表现出良好的效果。这项研究为制造和开发低成本的钛金属基纳米材料提供了新思路，这些材料未来可用于将排放的二氧化碳气体回收利用为有用的太阳能燃料。
