“…Compared with g-C 3 N 4 , A5À CN, N5À CN, and A5N5À CN without exception experience obvious red-shift and the absorption intensity in the ultraviolet and visible light region is significantly enhanced, which can be ascribed to the decoration of Ag and Ni(OH) 2 . [40,41] The improved light harvesting of samples can facilitate the generation of more photoinduced electrons and holes, which is consistent with the photocatalytic hydrogen production performance. Using the same method, the band gaps of A5À CN, N5À CN, and A5N5À CN are determined to be 2.65 eV, 2.68 eV, and 2.60 eV, respectively.…”

A series of ternary Ag/Ni(OH)2/g‐C3N4 composite photocatalysts were prepared by a facile method. The as‐prepared samples were characterized by powder X‐ray diffraction (XRD), Fourier transform infrared (FT‐IR), scanning electron microscopy (SEM), transmission electron microscopy (TEM), and UV‐vis diffuse reflectance spectra (DRS). Photocatalytic water splitting for hydrogen was carried out to evaluate the photocatalytic performance of the as‐prepared samples and the effect of Ag and Ni(OH)2 content was explored. The results indicated that the A5N5−CN sample shows the optimal hydrogen evolution of 1663.2 μmol g−1 h−1, which was 114.7 times higher than that of bulk g‐C3N4. The enhanced photocatalytic activity can be ascribed to the synergistic effect of cocatalysts Ag and Ni(OH)2.

“…Based on the obtained results and other related studies [16,63], the possible mechanism involved in the photocatalytic degradation of TC under visible light has been proposed and presented in Figure 10. Upon the irradiation of Cu 7 S 4 , the photocatalysts are excited, leading to the generation of photogenerated electron-hole pairs that have strong reducing and oxidizing powers, respectively.…”

In this paper, spherical-shaped pure phase djurleite (Cu31S16) and roxbyite (Cu7S4) nanoparticles were prepared by a solvothermal decomposition of copper(II) dithiocarbamate complex in dodecanthiol (DDT). The reaction temperature was used to control the phases of the samples, which were represented as Cu31S16 (120 °C), Cu31S16 (150 °C), Cu7S4 (220 °C), and Cu7S4 (250 °C) and were characterized by using X-ray diffraction (XRD), scanning and transmission electron microscopy (SEM and TEM), and absorption spectroscopy. The samples were used as photocatalysts for the degradation of tetracycline (TC) under visible light irradiation. The results of the study showed that Cu7S4 (250 °C) exhibited the best activity in the reaction system with the TC degradation rate of up to 99% within 120 min of light exposure, while the Cu31S16 (120 °C) system was only 46.5% at the same reaction condition. In general, roxbyite Cu7S4 (250 °C) could be considered as a potential catalyst for the degradation of TC in solution.

“…Electrochemistry represents an effective tool in many important applications. For instance, in wastewater treatment by removal of organic pollutants or drugs (such as antibiotic waste tetracycline hydrochloride) from wastewater [26,27]. In addition, it also represents a promising tool in the valorization of cellulose thanks to its green and sustainable features, as illustrated in Figure 1.…”

Humanity’s overreliance on fossil fuels for chemical and energy production has resulted in uncontrollable carbon emissions that have warranted widespread concern regarding global warming. To address this issue, there is a growing body of research on renewable resources such as biomass, of which cellulose is the most abundant type. In particular, the electrochemical reforming of biomass is especially promising, as it allows greater control over valorization processes and requires milder conditions. Driven by renewable electricity, electroreforming of biomass can be green and sustainable. Moreover, green hydrogen generation can be coupled to anodic biomass electroforming, which has attracted ever-increasing attention. The following review is a summary of recent developments related to electroreforming cellulose and its derivatives (glucose, hydroxymethylfurfural, levulinic acid). The electroreforming of biomass can be achieved on the anode of an electrochemical cell through electrooxidation, as well as on the cathode through electroreduction. Recent advances in the anodic electroreforming of cellulose and cellulose-derived glucose and 5-hydrooxylmethoylfurural (5-HMF) are first summarized. Then, the key achievements in the cathodic electroreforming of cellulose and cellulose-derived 5-HMF and levulinic acid are discussed. Afterward, the emerging research focusing on coupling hydrogen evolution with anodic biomass reforming for the cogeneration of green hydrogen fuel and value-added chemicals is reviewed. The final chapter of this paper provides our perspective on the challenges and future research directions of biomass electroreforming.
