Synthesis of photocatalytic nanomaterials for production of clean alternative energy

Abstract

Energy is one of the key fundamentals for economic progress in this era. However, energy is becoming one of the most disturbing problems at a global scale. Approximately 90% of the world’s energy supply is based on fossil fuels. Understandably this is causing some fear and worry that our energy resources have been largely depleted. On the other hand, the pollution and climate changes caused by fossil fuels are becoming a major source of concern worldwide. Due to this situation and the need for a cleaner environment, interest in alternative and renewable fuels for energy production has increased rapidly around the world. Many recent studies suggest that the direct use of hydrogen as a fuel may provide a much cleaner and far less expensive fuel alternative. In addition, Hydrogen is a promising fuel to replace depleting fossil fuels. However presently, almost commercial hydrogen production is still based on raw fossil materials. Thus, nowadays challenge is to produce hydrogen from renewable resources.
