Abstract：
Carbon dioxide (CO2) emission has been a global concern over the past few decades due to the increase in the demand of energy, a major source of which is fossil fuels. To mitigate the emission issues, as well as to find a solution for the energy needs, an ample load of research has been carried out over the past few years in CO2 reduction by catalysis. Bismuth, being an active catalyst both photocatalytically and electrocatalytically, is an interesting material that can be formed into oxides, sulphides, oxyhalides, etc. Numerous works have been published based on bismuth-based materials as active catalysts for the reduction of CO2. However, a proper understanding of the behavior of the active facets and the dependence of morphology of the different bismuth-based catalysts is an interesting notion. In this review, various bismuth-based materials will be discussed regarding their activity and charge transfer properties, based on the active facets present in them. With regard to the available literature, a summarization, including photocatalysis, electrocatalysis as well as photoelectrocatalysis, will be detailed, considering various materials with different facets and morphologies. Product selectivity, varying on morphological difference, will also be realized photoelectrochemically.
摘要：
在过去的几十年中，由于能源需求的增加，二氧化碳（CO2）排放一直是全球关注的问题。其主要来源是化石燃料。为了缓解排放问题，以及找到满足能源需求的解决方案，在过去的几年中，通过催化减少CO2已经进行了大量的研究。铋,作为光催化和电催化的活性催化剂，是一种有趣的材料，可以形成氧化物，硫化物,卤氧化物,等。已经发表了许多基于铋基材料作为还原CO2的活性催化剂的工作。然而,对不同铋基催化剂的活性面行为和形态依赖性的正确理解是一个有趣的概念。在这次审查中,将讨论各种铋基材料的活性和电荷转移特性，基于它们中存在的活跃方面。关于现有文献，总结，包括光催化,电催化以及光电催化，将是详细的，考虑具有不同方面和形态的各种材料。产品选择性,在形态差异上有所不同，也将实现光电化学。
