The photocatalytic activity of catalysts depends on the energy-harvesting ability and the separation or transport of photogenerated carriers. The light absorption capacity of graphitic carbon nitride（g-C3N4）-based composites can be enhanced by adjusting the surface plasmon resonance（SPR） of noble metal nanoparticles（e.g., Cu, Au, and Pd） in the entire visible region. Adjustments can be carried out by varying the nanocomponents of the materials. The SPR of noble metals can enhance the local electromagnetic field and improve interband transition, and resonant energy transfer occurs from plasmonic dipoles to electron–hole pairs via near-field electromagnetic interactions. Thus, noble metals have emerged as relevant nanocomponents for g-C3N4used in CO2photoreduction and water ***, recent key advances in noble metals（either in single atom, cluster, or nanoparticle forms） and composite photocatalysts based on inorganic or organic nanocomponent-incorporated g-C3N4nanosheets are systematically discussed, including the applications of these photocatalysts, which exhibit improved photoinduced charge mobility in CO2photoconversion and H2production. Issues related to the different types of multi-nanocomponent heterostructures（involving Schottky junctions, Z-/S-scheme heterostructures, noble metals, and additional semiconductor nanocomponents） and the adjustment of dimensionality of heterostructures（by incorporating noble metal nanoplates on g-C3N4forming 2D/2D heterostructures） are explored. The current prospects and possible challenges of g-C3N4composite photocatalysts incorporated with noble metals（e.g., Au, Pt, Pd, and Cu）, particularly in water splitting, CO2reduction, pollution degradation,and chemical conversion applications, are summarized.

Cooked rice and the vegetables like lettuce are common kitchen waste, which are carbonaceous materials and have the potential as feedstock for the production of activated carbon. Cooking is similar to hydrothermal treatment（HTC）, which might impact the subsequent activation of kitchen waste. In this study, the HTC of lettuce, rice, or their mixture and the activation of the resulting hydrochars were conducted. The results indicated that cross-polymerization between the N-containing organics from lettuce and the sugar derivatives from rice took place in their co-HTC, which significantly increased the hydrochar yield. Activation of the hydrochar from the coHTC generated the AC with a yield of 2 times that from direct activation of mixed lettuce/rice. However, the coHTC facilitated aromatization, reducing reactivity with K2C2O4in activation and producing the AC with main micropores and low specific surface area. Activation of the hydrochar from HTC of rice followed the above trend,while that from lettuce was the opposite. The organics in lettuce were thermally unstable and could not undergo sufficient aromatization. The activation of hydrochar from HTC of lettuce thus generated the AC with the lowest yield, but the highest specific surface area（1684.9 m2/g）, abundant mesopores, and superior capability for adsorption of tetracycline. However, the environmental impacts and energy consumption for the production of AC from the hydrochar of lettuce were higher than that from hydrochar of co-HTC.

Identification of natural substances with antioxidant properties is ongoing research for addressing issues related to oxidative stress especially attributed to environmental effects. Our previous study demonstrated that Lateolabrax japonicus peptides （LPH）， rich in Glu， Gly， and hydrophobic amino acids， exhibited remarkable antioxidant activity in vitro， with though its action mechanism yet to be revealed. Therefore， to assess the in vivo antioxidative properties of LPH， we employed H2O2to generate oxidative stress in Drosophila melanogaster model. Results indicated that LPH significantly prolonged the lifespan of Drosophila subjected to oxidative stress mostly mediated via LPH's enhancement of the antioxidant defense system and intestinal functions. Antioxidant effects were manifested by a decrease in malondialdehyde （MDA） levels， elevated superoxide dismutase （SOD）， catalase （CAT）， and glutathione peroxidase （GSH-Px） activities， decreased levels of reactive oxygen species （ROS） in intestinal epithelial cells， and the preservation of intestinal length. LPH effectively controlled the excessive proliferation and differentiation of oxidative stress-induced Drosophila intestinal stem cells. At the gene level， LPH upregulated the expression of antioxidant-related Nrf2 genes while concurrently downregulated mTOR expression level. Furthermore， high-throughput 16S rDNA sequencing revealed that the addition of LPH significantly influenced the diversity and abundance of the intestinal microbiota in H2O2-induced Drosophila. These findings provide a deeper understanding of the antioxidative mechanism of LPH， suggesting its potential applications in food industry and to be assessed using other in vivo oxidative stress models.
