Exclusive responsiveness to ultraviolet light (~3.2 eV) and high photogenerated charge recombination rate are the two primary drawbacks of pure TiO_(2). We combined N-doped graphene quantum dots (N-GQDs), morphology regulation, and heterojunction construction strategies to synthesize N-GQD/N-doped TiO_(2)/P-doped porous hollow g-C_(3)N_(4) nanotube (PCN) composite photocatalysts (denoted as G-TPCN). The optimal sample (G-TPCN doped with 0.1wt% N-GQD, denoted as 0.1% G-TPCN) exhibits significantly enhanced photoabsorption, which is attributed to the change in bandgap caused by elemental doping (P and N), the improved light-harvesting resulting from the tube structure, and the upconversion effect of N-GQDs. In addition, the internal charge separation and transfer capability of0.1% G-TPCN are dramatically boosted, and its carrier concentration is 3.7, 2.3, and 1.9 times that of N-TiO_(2), PCN, and N-TiO_(2)/PCN(TPCN-1), respectively. This phenomenon is attributed to the formation of Z-scheme heterojunction between N-TiO_(2) and PCNs, the excellent electron conduction ability of N-GQDs, and the short transfer distance caused by the porous nanotube structure. Compared with those of N-TiO_(2), PCNs, and TPCN-1, the H2 production activity of 0.1%G-TPCN under visible light is enhanced by 12.4, 2.3, and 1.4times, respectively, and its ciprofloxacin (CIP) degradation rate is increased by 7.9, 5.7, and 2.9 times, respectively. The optimized performance benefits from excellent photoresponsiveness and improved carrier separation and migration efficiencies. Finally, the photocatalytic mechanism of 0.1% G-TPCN and five possible degradation pathways of CIP are proposed. This study clarifies the mechanism of multiple modification strategies to synergistically improve the photocatalytic performance of 0.1% G-TPCN and provides a potential strategy for rationally designing novel photocatalysts for environmental remediation and solar energy conversion.

Background::Apoptotic cell-conditioned mesenchymal stem cells (AC-MSCs) exhibit stronger T cell suppressive ability via cyclooxygenase 2 (COX2)/prostaglandin E2 (PGE2);however, whether AC-MSCs exhibit enhanced therapeutic effects on systemic lupus erythematosus (SLE) remains unknown. Methods: Splenocytes from MRL/MPJ-Fas lpr (MRL /lpr) mice were cocultured with AC-MSCs, and the proportion of plasma cells was determined by flow cytometry. MSCs, AC-MSCs, COX2 knockdown MSCs, and COX2 knockdown AC-MSCs were infused into MRL/ lpr mice ( n = 10/group). Survival rates and lupus symptoms, including proteinuria, kidney injury, renal immune complex deposition, and autoantibody production, were assessed. Additionally, the number of plasma cells and serum levels of inflammatory cytokines were measured. Results::The AC-MSCs significantly inhibited plasma cells via PGE2 after 24 h coculture in vitro, whereas MSCs did not. In the MRL /lpr mice, AC-MSC treatment led to a significantly higher survival rate than phosphate-buffered saline (PBS) treatment (90% vs. 50%, p < 0.05). Moreover, AC-MSC infusion decreased urine protein levels as early as 1 week after administration (0.89 ± 0.55 mg/mL vs. 1.59 ± 0.60 mg/mL, p < 0.05, compared with PBS treatment). Administration of both MSCs and AC-MSCs reduced renal immunoglobulin G and complement C3 deposition, whereas COX2 knockdown MSCs and COX2 knockdown AC-MSCs did not. Serum anti-dsDNA antibody levels in AC-MSC-treated mice significantly decreased (0.40 ± 0.25 vs. 0.99 ± 0.58, p < 0.05), compared with PBS treatment, as well as the number of plasma cells in both the spleen ([2.14 ± 1.05] × 10^(6) vs. [8.02 ± 4.01] × 10^(6), p < 0.01) and renal-draining lymph nodes ([0.78 ± 0.68] × 10^(6) vs. [2.49 ± 1.45] × 10^(6), p < 0.05). Additionally, AC-MSCs inhibited the production of inflammatory cytokines, including interleukin-21, tumor necrosis factor-alpha, and monocyte chemoattractant protein-1. Conclusions::AC-MSCs enhanced the therapeutic
