A Design Framework for Portable Artificial Photosynthesizer: A Future Reality

Abstract

Global warming due to the addition of carbon dioxide (CO2) emissions is creating a threat to the environment and techniques to reduce the impact of CO2 gains importance and attention of researchers to equip a new technology paradigm to reduce the emissions. Even though naturally available, petroleum products are advised to consume less, unlike any other commodities that are available in the market. This is due to the negative effects of the petroleum products as they emit carbon dioxide due to partial combustion. Source correction is the best solution to any problem. Reducing the utilization of the petroleum products in the transportation sector may not be possible immediately. So, there is an immediate need to solve the problem which can add value to the environment by consuming the petroleum products. Photosynthesis places an important role in the balancing of oxygen and carbon dioxide ratios. The process of artificial photosynthesis through catalytic reactions still stands a complex nature. This work aims to develop a design model for portable artificial photosynthesizer through catalytic reactions which can be easily fixed to an exhaust unit for automobiles. Converting CO2 to O2 through artificial photosynthesis through this portable device is the prime aim of this design which helps to add oxygen to the environment instead of contributing to CO2 emissions. A supported catalyst and a catalytic process have been developed for the conversion of CO2 + H2O (in the form of steam) to some efficient carbon product. The catalyst simultaneously splits water into hydrogen and oxygen, and conversion of carbon dioxide into hydrocarbon under very mild reaction conditions and at atmospheric pressure. Artificial photosynthesis portable device once tested experimentally for the desired efficiency can be a breakthrough in the environmental technology with the demand to consume more petroleum products giving thrust to both economy and environment.
