Nanotechnology is the development of molecular-scale functional systems. While nanoparticles have been a part of our daily lives for a long time, the nanotechnology sector has grown rapidly in the last two decades. Nanotechnology is being used in a variety of ways to improve the environment and produce more efficient and cost-effective energy, including reducing pollution during the manufacturing of materials, producing solar cells at an economical price, clearing away organic chemicals polluting groundwater, and cleaning volatile organic compounds (VOCs) from the air.
The current global energy and environmental predicament has prompted a greater emphasis on renewable and ecologically acceptable energy sources. Nanotechnology is expected to play a key role in the development of new, more effective ways for storing hydrogen, capturing CO2, and converting energy. Understanding and designing nanometerscale catalysts is critical in this discipline because materials can acquire novel properties at this scale. Single particles, aggregated particles, and porous materials can all be used as nanocatalysts. High expectations are being placed in nanotechnological optimized energy production and storage processes or products, which are currently in the development phase and are expected to contribute considerably to future climate protection and energy solutions.
