“…In addition, the use of PVP as a surfactant prevents crystal growth, favoring the formation of small-scale particles. According to Avila-L opez et al [30], the use of low concentration solutions favors forming irregularly shaped nanoparticles. Thus, the surfactant/precursor ratio (5:1) used in this work was sufficient to guarantee forming particles with small diameters.…”

“…The photogenerated e – in the CB of Bi 12 SiO 20 and the photogenerated h + in the VB of BiO 2– x recombine facilitated by the built-in electric field, thus establishing an S-scheme process. Since BiO 2– x has a more negative E CB than CO 2 /CH 3 OH (−0.38 V), the e – in the CB position of BiO 2– x are kept to convert CO 2 to methanol . Moreover, Bi 12 SiO 20 has a more positive VB potential energy than H 2 O/H + (1.23 V).…”

Photocatalytic reduction of carbon dioxide to chemical fuels is an attractive route to generate renewable energy and curtail the green house effect. However, it remains a great challenge to explore cost-effective photocatalysts using natural and readily available clay minerals. In this work, one-dimensional natural palygorskite (Pal) is treated with acid to remove most of the metal ions from the silica framework, and bismuth ions are incorporated to grow two-dimensional (2D) bismuth silicate (Bi 12 SiO 20 ) nanosheet under a microwave-hydrothermal process. Excess Bi ions generate bismuth oxide (BiO 2−x ) nanoparticles that respond to nearinfrared (NIR) light and coprecipitate on the surface of Bi 12 SiO 20 , which forms a well-defined S-scheme Bi 12 SiO 20 /BiO 2−x heterojunction facilitating the charge transfer and maintaining high redox potentials. The abundant active sites on the 2D Bi 12 SiO 20 sheet and the oxygen vacancies in BiO 2−x particles are found to favor the cooperative activation and adsorption of CO 2 . The influence of various amounts of BiO 2−x on CO 2 reduction performance is explored. Bi 12 SiO 20 /BiO 2−x -30 wt % shows the best photocatalytic reaction rate at 31.16 μmol•g −1 •h −1 for CH 3 OH formation during sunlight irradiation. In NIR light, the Bi 12 SiO 20 / BiO 2−x -30 wt % even achieves a CH 3 OH generation rate of 17.1 μmol•g −1 •h −1 . The current study potentially provides a sustainable approach for CO 2 conversion.

“…Ávila-López et al [ 43 ] prepared CuO with an SSA of 351 m 2 /g by using copper acetate hydrate (Cu(CH 3 COO) 2 ·xH 2 O) as the metal oxide precursor and sodium citrate (Na 3 C 6 H 5 O 7 ) as a surfactant. A sonochemical treatment was performed at 100 W for 15–60 min followed by washing and drying at 80 °C.…”

Ultrasounds are commonly used in medical imaging, solution homogenization, navigation, and ranging, but they are also a great energy source for chemical reactions. Sonochemistry uses ultrasounds and thus realizes one of the basic concepts of green chemistry, i.e., energy savings. Moreover, reduced reaction time, mostly using water as a solvent, and better product yields are among the many factors that make ultrasound-induced reactions greener than those performed under conventional conditions. Sonochemistry has been successfully implemented for the preparation of various materials; this review covers sonochemically synthesized nanoporous materials. For instance, sonochemical-assisted methods afforded ordered mesoporous silicas, spherical mesoporous silicas, periodic mesoporous organosilicas, various metal oxides, biomass-derived activated carbons, carbon nanotubes, diverse metal-organic frameworks, and covalent organic frameworks. Among these materials, highly porous samples have also been prepared, such as garlic peel-derived activated carbon with an apparent specific surface area of 3887 m2/g and MOF-177 with an SSA of 4898 m2/g. Additionally, many of them have been examined for practical usage in gas adsorption, water treatment, catalysis, and energy storage-related applications, yielding satisfactory results.
