Energy is a key attribute that is used to evaluate the economic development of any country. The demand for energy is going to rise in developing countries and will be 67% of global use by 2040. The energy surge in these rising economies will be responsible for 60-70% of the global greenhouse gas emissions. The quest for higher energy motivates technological development to curb the climate change occurring with GHG emissions. Carbon dioxide is one of the primary greenhouse gases in the atmosphere. Current work is intended to give an updated review on the different routes of carbon dioxide utilization that are catalytic route, photocatalytic route, electrocatalytic route, microwave plasma route, and biocatalytic route. These routes are capable of converting CO into different valuable products such as formic acid, methanol, and di-methyl ether (DME), which are majorly derived from biomass and/or fossil fuels (coal gasification and/or natural gas). This work investigates the effect of different routes available for the production of value-added products by CO reduction, discusses various challenges that come across the aforementioned routes, and shares views on future scope and research direction to pave new innovative ways of reducing CO from the environment.
能源是评估任何国家经济发展的关键属性。发展中国家的能源需求将上升，到 2040 年将占全球使用量的 67%。这些新兴经济体的能源热潮将导致全球温室气体排放的 60-70%。对更高能源的追求促使技术发展以遏制温室气体排放引起的气候变化。二氧化碳是大气中主要的温室气体之一。目前的工作旨在对二氧化碳利用的不同途径进行更新综述，包括催化途径、光催化途径、电催化途径、微波等离子体途径和生物催化途径。这些途径能够将 CO 转化为不同有价值的产品，如甲酸、甲醇和二甲醚 (DME)，主要来自生物质和/或化石燃料（煤气化和/或天然气）。这项工作研究了 CO 还原生产附加值产品的各种途径的效果，讨论了上述途径中遇到的各种挑战，并就未来的范围和研究方向发表了看法，为从环境中减少 CO 开辟新的创新途径。
