Catalysis and Chemical Reactions
Electrocatalysis: Silicon nanoparticles are used in electrocatalytic reactions, such as water splitting for hydrogen production. In hydrogen evolution reactions (HER), Si-NPs act as efficient catalysts, and the ethanol dispersion ensures uniform distribution of the nanoparticles, increasing their reactivity.
Organic Synthesis: In organic chemistry, silicon nanoparticles can catalyze the hydrosilylation of organic compounds. The dispersion of Si-NPs in ethanol ensures better reactivity and selectivity during the reaction, which is useful for the synthesis of silanes, siloxanes, and other important chemicals.
Reduction and Oxidation Reactions: Silicon nanoparticles in ethanol dispersion are also effective in reduction and oxidation processes. For example, they can catalyze the reduction of organic compounds or aid in the oxidation of alcohols to aldehydes and acids, making them useful in the pharmaceutical and fine chemicals industries.
Energy Storage and Conversion
Lithium-Ion Batteries: Silicon nanoparticles are a promising anode material for lithium-ion batteries (LIBs) due to their high theoretical capacity for lithium storage. However, silicon undergoes significant volume expansion during charging and discharging cycles. Ethanol dispersion helps stabilize the nanoparticles and prevent aggregation, improving the cycle life and capacity retention of LIBs. Additionally, ethanol dispersions are used to prepare silicon-based nanocomposite anodes, which enhance the overall performance of the batteries.
