Synergistic Promotion of Selective Oxidation of Glycerol to C3 Products by Mo-Doped BiVO4-Coupled FeOOH Co-Catalysts Through Photoelectrocatalysis Process
The Mo:BiVO4/FeOOH photoelectrode was synthesized through the deposition of FeOOH onto the surface of the Mo:BiVO4 photoelectrode. The composite photoelectrode demonstrated a photocurrent of 1.8 mA·cm−2, which is three times greater than that observed for pure BiVO4. Furthermore, the glycerol conversion rate was recorded at 79 μmol·cm−2·h−1, approximately double that of pure BiVO4, while the selectivity for glyceraldehyde reached 49%, also about twice that of pure BiVO4. The incorporation of Mo has been shown to enhance the stability of the BiVO4. Additionally, Mo doping improves the efficiency of electron-hole transport and increases the carrier concentration within the BiVO4. This enhancement leads to a greater number of holes participating in the formation of iron oxyhydroxide (FeOOH), thereby stabilizing the FeOOH co-catalyst within the glycerol conversion system. The FeOOH co-catalyst facilitates the adsorption and oxidation of the primary hydroxyl group of glycerol, resulting in the cleavage of the C−H bond to generate a carbon radical (C). The interaction between the carbon radical and the hydroxyl group produces an intermediate, which subsequently dehydrates to form glyceraldehyde (GLAD).

A World Without Enemies
This article discusses Chen Kaige’s film adaptation of the Yuan drama The Orphan of Zhao. I focus on the two most important changes that Chen has made — namely, Cheng Ying substituting his own son for the Orphan and the Orphan seeking revenge on Tu’an Gu. The rewriting of these two episodes almost entirely alters the meaning of the story and imbues it with modern significance. My investigation concentrates on four questions. How are the main characters’ identities reconstructed beyond traditional blood ties? Whose revenge is the story about? How does the retelling reshape the tragedy? And, finally, is there a chance of redemption in revenge? Chen Kaige questions traditional values that mark the original story of vengeance, such as sacrifice, loyalty, and righteousness, and reflects on the issues that reconstitute the meaning of revenge—identity, individuality, authority, and redemption. The many contradictions in the script reveal not only different interpretations of the story by Chen and his collaborators but also the inner tension in Chen’s insistence on refashioning the traditional theme of revenge in a modern and idealist fashion. Chen’s adaptation, I argue, simultaneously gives a decidedly modern spin to the story and is limited by modern conditions.

Synergistic Promotion of Selective Oxidation of Glycerol to C3 Products by Mo-Doped BiVOsub.4-Coupled FeOOH Co-Catalysts Through Photoelectrocatalysis Process
The Mo:BiVO[sub.4]/FeOOH photoelectrode was synthesized through the deposition of FeOOH onto the surface of the Mo:BiVO[sub.4] photoelectrode. The composite photoelectrode demonstrated a photocurrent of 1.8 mA·cm[sup.−2], which is three times greater than that observed for pure BiVO[sub.4]. Furthermore, the glycerol conversion rate was recorded at 79 μmol·cm[sup.−2]·h[sup.−1], approximately double that of pure BiVO[sub.4], while the selectivity for glyceraldehyde reached 49%, also about twice that of pure BiVO[sub.4]. The incorporation of Mo has been shown to enhance the stability of the BiVO[sub.4]. Additionally, Mo doping improves the efficiency of electron-hole transport and increases the carrier concentration within the BiVO[sub.4]. This enhancement leads to a greater number of holes participating in the formation of iron oxyhydroxide (FeOOH), thereby stabilizing the FeOOH co-catalyst within the glycerol conversion system. The FeOOH co-catalyst facilitates the adsorption and oxidation of the primary hydroxyl group of glycerol, resulting in the cleavage of the C−H bond to generate a carbon radical (C).
