In this study, the catalytic activity of Cu-derived oxide catalysts in glycerol hydrogenolysis was investigated and the effect on the selectivity of 1,2-propanediol (1,2-PDO) with the different Cu/Al molar ratios was observed. The glycerol conversion/1,2-PDO selectivity was found to be dependent on ...

In recent years, the conversion of carbon dioxide (CO$_2$) to value-added products has become an area of great interest, both from an industrial and environmental perspective. Here we have successfully synthesized TiO$_2/CeO_2$-based catalysts by exo- and endo-template and use for direct conversion ...

This study investigates the degradation of N-methyl-2-pyrrolidone (NMP) by UV-C and UV-C/PMS-treatment processes. The degradation of NMP was less than 2% by UV-C photolysis. To enhance the degradation, PMS was used as a source of sulphate (SO$_4$$^•$$^−$) and hydroxyl (HO$^•$) radicals in the UV-C p ...

In the present study, a Bi$_2$WO$_6$/ZnWO$_4$ photocatalyst was successfully constructed by a modified hydrothermal synthesis method with different molar concentrations of Bi$_2$WO$_6$ with respect to ZnWO$_4$. The variation in molar concentrations of Bi$_2$WO$_6$ changed the photocatalytic properti ...

Bisphenol A (BPA) is a toxic substance that is released into the environment mainly from paint, polymer, plastics and pharmaceutical industries. In this study, spinel Co$_3$O$_4$ consisting of Co$^{2+}$/(Co$^{3+}$)$_2$O$_4$ nanospheres with excellent specific surface properties were systematically s ...

4-Carboxybenzaldehyde (4-CBA), a major component of purified terephthalic acid wastewater, is toxic to living organisms and required to be removed before the discharge of treated wastewater in a natural water body. In this work, the adsorptive removal of 4-CBA was studied using bagasse fly ash (BFA) ...

The rigorous production and consumption of antibiotics globally have necessarily resulted in enormous volumes of these drugs being released into the environment, and several strategies have lately been proposed to reduce antibiotic contamination. As a result, bismuth-based photocatalysts have receiv ...
