Low-Dimensional Nanomaterial Systems Formed by IVA Group Elements Allow Energy Conversion Materials to Flourish

“…Although silicon has been used for research in solar power generation due to its excellent photochemical properties, it is not suitable for use as a photothermal material for photothermal conversion due to its poor absorption of low-wavelength sunlight. Initially, the photothermal material was modified by loading silicon nanoparticles with silicon as a modifier [ 89 ], and the transformation of the material from hydrophilic to hydrophobic was achieved, as shown in Figure 8 b–d, which improved the absorption of sunlight ( Figure 8 e). Then by doping gold, silver, and other precious metals with silicon [ 90 , 91 ], the researchers realized the absorption of the full band of sunlight, which is used as a photothermal material generated by solar-thermal steam to study.…”

A bioinspired 3D solar evaporator with balanced water supply and evaporation for highly efficient photothermal steam generation

“…[2][3][4][5][6][7][8][9][10] The past few years have seen a dramatic advance in boosting the water evaporation rate and light-to-heat conversion efficiency by optimization of photothermal materials [11][12][13] and elaborative design of the geometrical morphology of ISSG evaporators. [14][15][16][17][18][19] To date, a series of promising photothermal materials, such as polymers, [20][21][22][23] semiconductors, [24][25][26][27] metal nanoparticles [28][29][30] and carbonous materials, [31][32][33][34][35][36] have been used to construct ISSG evaporators. Among these materials, carbon-based ones such as graphene, carbon nanotubes and carbon bres have attracted tremendous attention due to their strong broadband light absorption and outstanding chemical and thermal stabilities.…”
