Review on Template Removal Techniques for Synthesis of ...

Feb 19, 2022 Wang et al. used the SDBD reactor to eliminate the P123 copolymer from SBA-15. The FT-IR spectra of as-synthesis SBA-15, SBA-15-C, and SBA-15-DBD are illustrated in Figure 10(b). Normally, the aliphatic stretching and bending vibrations are observed at wavenumbers between 2950 and 2840 cm –1 and 1500–1350 cm –1, respectively.

Development and Recent Progress on Ammonia Synthesis ...

In the conventional Haber–Bosch process, fossil fuels such as natural gas and coal are normally used as the energy sources for ammonia synthesis, releasing millions of tonnes of CO 2 to the atmosphere, which is about 1–2% of the global CO 2 emission. [1, 4, 5] The use of low-carbon renewable energy sources has been proposed to produce green ...
