Abstract Anthropogenic activities powered by the burning of fossil fuels have caused excessive emissions of carbon dioxide (CO2) to the atmosphere. This has a negative impact on our environment. One promising approach to reduce the concentration of atmospheric CO2 is to convert it to useful products. This could be achieved via the electrochemical reduction of CO2 using renewable electricity. Methanol (CH3OH), a valuable fuel and feedstock, is one of the CO2 electroreduction products. However, its formation, thus far, has been plagued by the inadequacy of functional electrocatalysts. In this review, we summarize progresses made in the development of methanol-selective electrocatalysts, which provides us with a basis to discuss the underlying challenges of electroreducing CO2 to methanol.

Abstract: Electricity production using conventional energy sources is associated with serious environmental problems like emission of pollutants, global warming and social problems. The world’s CO2 emissions are projected to rise from 29.0 billion MT in 2006 to 33.1 billion MT in 2015 and 40.4 billion MT in 2030. This increase in emissions indicates more global warming. The Indian Ministry of New and Renewable Energy (MNRE) has been supporting programs for the development of renewable energy sources which are not only unlimited but environmentally friendly — like biomass, solar, small hydro, wind, etc. If biomass is used sustainably, there is no net carbon emission over the time of a cycle of biomass production.Waste management is an important issue today. To handle the ever growing problem of waste, residents and companies are constantly looking for the best and least expensive methods. Types of waste generated by the Indian Institute of Technology Roorkee (IITR) include kitchen waste, municipal solid waste, sewage waste, and waste cooking oil. By utilizing biodegradable waste out of total waste clean energy can be generated and waste disposal problems solved.DOI: http://dx.doi.org/10.3126/hn.v9i0.7071 Hydro Nepal Vol.9 July 2011 38-43

<div>Electrochemical reduction of CO2 to useful chemical and fuels in an energy efficient way is currently an expensive and inefficient process. Recently, low-cost transition metal-carbides (TMCs) are proven to exhibit similar electronic structure similarities to Platinum-Group-Metal (PGM) catalysts and hence can be good substitutes for some important reduction reactions. In this work, we test graphenesupported WC (Tungsten Carbide) nanocluster as an electrocatalyst for the CO2 reduction reaction. Specifically, we perform DFT studies to understand various possible reaction mechanisms and determine the lowest thermodynamic energy landscape of CO2 reduction to various products such as CO, HCOOH, CH3OH, and CH4. This in-depth study of reaction energetics could lead to improvements and develop more efficient electrocatalysts for CO2 reduction.<br></div>
