Solar-light-driven photocatalytic conversion of monosaccharide by oxygen-doped graphitic carbon nitride/artificial steel converter slag composite

Photo-, electro-, and photoelectro-catalytic conversion of glucose into high value-added products

“…Meanwhile, it can also be cost-effectively prepared on a large scale via a simple preparation method. 52,53 However, the low visible light utilization efficiency of g-C 3 N 4 limits its direct application in photocatalysis. Atomic doping, 54 elemental ratio modulation, 55 and coupling with other semiconductors 51 or conductors 56 can effectively improve the activity of g-C 3 N 4 for photocatalytic conversion of glucose.…”

“…Atomic doping, 54 elemental ratio modulation, 55 and coupling with other semiconductors 51 or conductors 56 can effectively improve the activity of g-C 3 N 4 for photocatalytic conversion of glucose. Srikhaow et al 53 reported a photocatalyst consisting of oxygen-doped graphite carbon nitride and artificial steel slag with heterojunctions for the conversion of glucose to LA, which exhibited glucose conversion of 99% and LA yield of 90% under simulated solar irradiation (Fig. 4a).…”

Mg-modified graphitic carbon nitride/converter slag composites as an efficient photocatalyst for sugar conversion

“…26 Meanwhile, CS has high iron oxide contents (above 20%) and swelling properties and faces limitations in civil engineering applications. 27 Furthermore, the steel-making industry, a prominent CO 2 emitter in Japan, relies on coke as a reducing agent for iron ore, currently irreplaceable with H 2 . Due to the existence of photocatalytic active compounds such as iron oxide in CS, it has been recently explored and developed as a low-cost and resource-efficient photocatalyst for the production of H 2 and degradation of organic pollutants.…”

Highly Efficient Base-Catalyzed Valorization of Food Waste into Lactic Acid at Mild Conditions with the Pretreatment Using HCl Recovered from PVC

“…In comparison to fermentation, the chemical conversion of food waste (FW) into high-value chemicals presents an ostensibly more straightforward alternative characterized by shorter retention times and simplified operational processes. Recent fundamental research endeavors have explored the enhancement of lactic acid (LA) yields derived from carbohydrates via solvent thermal methods, employing a variety of catalysts. − Nevertheless, these investigations have predominantly employed intricate catalysts and model substrates such as glucose, rather than real food waste, rendering them less amenable to industrial-scale implementation.…”
