This remarkable improvement can be attributed to the enhanced visible light absorbance, improved surface area and charge carrier separation and transfer ability.
The improved efficiency was due to the role of the MTSs in improving surface area and light harvesting properties, as demonstrated by N2 adsorption/desorption isotherm, UV-visible light absorption, reflectance spectroscopy, incident photon-to-current efficiency (IPCE), and electrochemical impedance spectroscopy (EIS) analyses.
Catalyst characterization shows that addition of La2O3 up to 5 wt% improves surface area, CO2 adsorption capacity, Ni reducibility and metal dispersion, as well as reduces support acidity.
It has been reported that substitution of Cs+ for H+ in CsxH3-xPW12O40 catalysts improved surface area and thermal stability compared to parent acids, the surface area is the largest when x = 2.5 [15].
In particular, it highlights some of the critical roles and functions of anodes in MFCs, strategies available for improving surface areas of anodes, dominant performance of stainless-steel based anode materials, and the emerging benefits of inclusion of nanomaterials.
Au nanoparticles were fabricated on the Indium Tin Oxide coated glass (ITO) electrode by electrochemical deposition to improve the surface area to provide better electron-transfer kinetics, and higher background charging current.
Suitable contents of Ca could improve the surface area of the sample and enhance the conversion of DBT.
Assembling the Fe3O4@PPy core-shell material with RGO sheets could largely improve their surface area, pore volume, and enhance their chemical stability in acid and alkaline solution.
Further steam activation of the carbon monolith can significantly improve the surface area to 2422 m2 g−1 while still maintaining the ordered mesostructure.
Then we found that the CV treatment can be used to yield a roughened NiCu surface; thereafter, the selective dissolution of Cu can be used to further improve the surface area.
