“…The core-shelled TiO 2 @RP heterostructures were synthesized through the vaporization-deposition (VP) method (Figure 1a). [30][31][32] TiO 2 NRs were first prepared by calcinating the H 2 Ti 3 O 7 nanotube precursor and then mixed with various amounts of washed RP powders at 600 °C. During this process, RP vaporized in the vacuum ampoule and was deposited onto the TiO 2 NR surface during cooling to obtain TiO 2 @RP.…”

most frequent among females (the ratio between affected men and women is 2:1). [1,2] Approximately 270 000 new cases of RCC and 116 000 RCC-related deaths are reported worldwide per year. [3] Among the reported patients, clear cell RCC (ccRCC) cases account for 70-80%. [4] The cure rate of advanced ccRCC patients with a 5-year survival rate is as low as 11.7%, so efficient treatment is necessary. [5,6] Surgery is the most common treatment for ccRCC. However, with the high invasiveness and high resistance to chemotherapeutic agents, advanced ccRCC is difficult to cure once metastasis occurs. [7] In recent years, therapeutics focused on killing cancer cells via nanomaterial-based phototoxicities, such as photodynamic therapy (PDT) and photothermal therapy (PTT), have been widely studied. [8,9] PDT is an effective clinical approach that uses a photoactivatable compound as a photosensitizer and irradiation with appropriate wavelength light. Under illumination, the photosensitizer can be activated as a generator of reactive oxygen species (ROS) to kill cancer cells efficiently. PTT is also an effective means of cancer treatment, in which photothermal agents can catalyze the production of local heat under illumination to kill cancer cells. [9] PTT can increase the blood flow and Clear cell renal cell carcinoma (ccRCC) is a serious and tenacious disease. Photodynamic therapy (PDT) and photothermal therapy (PTT) are effective means of cancer treatment. However, PDT combined with PTT has been rarely reported in ccRCC treatment. In the present study, by developing the core-shell structured TiO 2 @red phosphorus nanorods (TiO 2 @RP NRs) as a photosensitizer, the feasibility and effectiveness of synchronous PDT and PTT treatments for ccRCC are demonstrated. The core-shell structured TiO 2 @ RP NRs are synthesized to drive the PDT and PTT for ccRCC, in which the RP shell is the sensitizer even in the near-infrared (NIR) region. The optimized TiO 2 @RP NRs can respond to NIR and produce local heat under irradiation. The NRs are estimated in ccRCC treatments via cell counting kit-8 assay, propidium iodide staining, qRT-PCR, and reactive oxygen species (ROS) probes in vitro, while terminal deoxynucleotidyl transferase dUTP nick-end labeling is conducted in vivo. After NIR irradiation, TiO 2 @RP NRs can efficiently kill ccRCC cells by producing local heat and ROS and cause low injury to normal kidney cells. Furthermore, treatment with TiO 2 @RP NRs and NIR can kill significant numbers of deep-tissue ccRCC cells in vivo. This work highlights a promising photo-driven therapy for kidney cancer.

“…The calculated band positions revealed the reaction between electrons and O 2 for the generation of H 2 O 2 species and O 2 − radicals during the redox reactions. 361 Cooperating with H + ions, these ROS could augment the effectiveness of TiO 2 @RP for microbial disinfection due to their powerful oxidation capacity. The production of oxidizing radicals was further boosted via the effective spatial separation and transfer of light-induced charge carriers, hence bestowing the TiO 2 @RP hybrid photocatalytic system with exceptional bacterial disinfection activity.…”

Photocatalysis is a perennial solution that promises to resolve deep-rooted challenges related to environmental pollution and energy deficit through harvesting the inexhaustible and renewable solar energy. To date, a cornucopia of photocatalytic materials has been investigated with the research wave presently steered by the development of novel, affordable, and effective metal-free semiconductors with fascinating physicochemical and semiconducting characteristics. Coincidentally, the recently emerged red phosphorus (RP) semiconductor finds itself fitting perfectly into this category ascribed to its earth abundant, low-cost, and metal-free nature. More notably, the renowned red allotrope of the phosphorus family is spectacularly bestowed with strengthened optical absorption features, propitious electronic band configuration, and ease of functionalization and modification as well as high stability. Comprehensively detailing RP’s roles and implications in photocatalysis, this review article will first include information on different RP allotropes and their chemical structures, followed by the meticulous scrutiny of their physicochemical and semiconducting properties such as electronic band structure, optical absorption features, and charge carrier dynamics. Besides that, state-of-the-art synthesis strategies for developing various RP allotropes and RP-based photocatalytic systems will also be outlined. In addition, modification or functionalization of RP with other semiconductors for promoting effective photocatalytic applications will be discussed to assess its versatility and feasibility as a high-performing photocatalytic system. Lastly, the challenges facing RP photocatalysts and future research directions will be included to propel the feasible development of RP-based systems with considerably augmented photocatalytic efficiency. This review article aspires to facilitate the rational development of multifunctional RP-based photocatalytic systems by widening the cognizance of rational engineering as well as to fine-tune the electronic, optical, and charge carrier properties of RP.
