“…Meanwhile, the lowest impedance of the Z-scheme CuO@GDY heterojunction was presented among all samples, demonstrating its superior conductivity and charge transfer capacity (Figure S6). , The enhanced photocurrent and conductivity of CuO@GDY implied that effectively accelerated photogenerated charge transfer between the two semiconductors inside the interface was due to the Z-scheme heterostructure, which could play a positive effect on NIR-excited photocatalytic activity . To confirm its NIR-photocatalytic O 2 -producing ability, the photocatalytic O 2 generation mediated by CuO@GDY upon the 808 nm laser illumination was detected with a dissolved oxygen instrument.…”

Photon radiotherapy is a common tool in the armory against tumors, but it is limited by hypoxia-related radioresistance of tumors and radiotoxicity to normal tissues. Here, we constructed a spatiotemporally controlled synergistic therapy platform based on the heterostructured CuO@Graphdiyne (CuO@GDY) nanocatalyst for simultaneously addressing the two key problems above in radiotherapy. First, the in situ formed Z-scheme CuO@GDY heterojunction performs highly efficient and controlled photocatalytic O2 evolution upon near-infrared (NIR) laser stimulation for tumor hypoxia alleviation. Subsequently, the CuO@GDY nanocatalyst with X-ray-stimulated Cu+ active sites can accelerate Fenton-like catalysis of ·OH production by responding to endogenous H2O2 for the selective killing of tumor cells rather than normal cells. In this way, the sequential combination of NIR-triggered photocatalytic O2 production and X-ray-accelerated Fenton-like reaction can lead to a comprehensive radiosensitization. Overall, this synergism underscores a controllable and precise therapy modality for simultaneously unlocking the hypoxia and non-selectivity in radiotherapy.

“…Many researchers have shown that Ce0/Fe0 nanoparticles tend to agglomerate to form bulky particles because of anisotropic dipolar interactions, which reduce their catalytic activities [ 63 ]. Thus, Wang et al developed Ce0/Fe0-rGO) composites where Ce0/Fe0 was anchored on reduced graphene oxide to enhance its properties [ 66 ].…”

“…In this case, the Cu of CuO was complexed with g-CN, which formed a dual reaction center based on the metal-O bridge [ 75 ]. Correspondingly, in situ Co-based Fenton-like catalysts were synthesized, in which Co species were modified into the framework of the graphitic carbon nitride (g-C 3 N 4 ) substrate through C-O-Co chemical bonding [ 66 ]. The Fenton oxidation reaction is simple to operate and can effectively oxidize and degrade refractory organics in wastewater, but there are problems, such as insufficient mineralization of the organics, secondary pollution caused by a large amount of iron sludge, and a low utilization of H 2 O 2 [ 26 ].…”

Carbon-based nanomaterials (CBM) have shown great potential for various environmental applications because of their physical and chemical properties. The unique hybridization properties of CBMs allow for the tailored manipulation of their structures and morphologies. However, owing to poor solar light absorption, and the rapid recombination of photogenerated electron-hole pairs, pristine carbon materials typically have unsatisfactory photocatalytic performances and practical applications. The main challenge in this field is the design of economical, environmentally friendly, and effective photocatalysts. Combining carbonaceous materials with carbonaceous semiconductors of different structures results in unique properties in carbon-based catalysts, which offers a promising approach to achieving efficient application. Here, we review the contribution of CBMs with different dimensions, to the catalytic removal of organic pollutants from wastewater by catalyzing the Fenton reaction and photocatalytic processes. This review, therefore, aims to provide an appropriate direction for empowering improvements in ongoing research work, which will boost future applications and contribute to overcoming the existing limitations in this field.
