Kinetic and Thermodynamic Study of Corncob Hydrolysis in Phosphoric Acid with Low Yield of Bacterial Inhibitors

Building a bridge from solid wastes to solar fuels and chemicals via artificial photosynthesis

“…The benefits of PR reaction are often summed up as three points when compared with photocatalytic overall water splitting (Figure 4): (i) waste oxidation reaction with less energy input replaces the OER with sluggish four‐electron transfer kinetics, thus improving the HER activity; (ii) the substitution of solid waste oxidation for OER prevents the back reaction of H 2 and O 2 ; (iii) waste solid resources are utilized and further converted into high‐value chemicals. Specifically, compared with OER (Gibbs free energy change, Δ G = 237 kJ mol −1 ), the oxidation reaction of solid waste, such as PLA and glucose oxidation with the Δ G values of 185 and 115 kJ mol −1 , respectively, enables a lower thermodynamic barrier, which contributes to the reduction of the overall energy demanding 75–77 . Besides, compared with conventional heat‐assisted strategy toward solid waste catalytic conversion under high temperature or high pressure, PR strategy can realize the waste upgrading under a mild atmosphere and meanwhile obtain hydrogen resource.…”

[75][76][77] Besides, compared with conventional heat-assisted strategy toward solid waste catalytic conversion under high temperature or high pressure, PR strategy can realize the waste upgrading under a mild atmosphere and meanwhile obtain hydrogen resource. Apart from the aforementioned PLA and glucose, other solid wastes with high enthalpy and reproducibility, such as PET, fructose, and 5-hydroxymethyfurfural, have been also served as feedstocks to accelerate the HER process.…”
