Hydrogen Production Using Modern Photocatalysts

Abstract

Fossil fuels play a powerful role in the global economy and are therefore referred to as strategic raw materials. However, their massive use around the world is associated with concerns about the sufficiency of energy sources for future generations. Currently, fossil fuel resources are heavily depleted, with limited supplies. According to forecasts, the demand for energy will constantly increase, so it is necessary to find a solution that reconciles the ever-increasing demand for energy with the need to protect the environment. The main solution to this problem is to acquire energy from renewable resources, especially in the direction of obtaining alternative substitutes for transportation fuels. One of the main alternative fuels that can replace existing fossil fuels is hydrogen. An efficient way to obtain this compound is through the use of modern photocatalysts. Hence, the purpose of this paper is to review the recent literature on the effective use of catalysts in photocatalytic processes (e.g., glycerol conversion) that enable the synthesis of hydrogen.

Non-Metal Doping as a First-Principles Study for Promoting the Hydrogen Evolution of Two-Dimensional Electride Y2C Electrocatalysts

“…Approximately 80% of this demand for energy will still come from traditional fossil fuels, and the extensive use of these fuels can result in serious environmental issues [3]. It is critical to locate clean, plentiful, and renewable energy sources in order to reduce environmental pollution and solve the world's energy dilemma [4][5][6][7][8][9]. Hydrogen's zero-pollution characteristic has made it a potential substitute for fossil fuels [9][10][11][12].…”
