“…Generally, morphological changes could affect the nanocatalyst materials’ physical and chemical properties. Factors such as structure, dimensionality, morphology and size of inorganic nanomaterials directly impact their functional properties, thus affecting their catalytic activity and selectivity [ 34 , 35 ]. Nanomaterials have unique optical, electrical, magnetic, catalytic and mechanical properties closely related to crystal morphology and morphology.…”

Photo(electro)catalytic nitrogen fixation technology is a promising ammonia synthesis technology using clean solar and electric energy as the driving energy. Abundant nitrogen and water as raw materials uphold the principle of green and sustainable development. However, the generally low efficiency of the nitrogen reduction reaction has seriously restricted the application and development of this technology. The paper introduces the nitrogen reduction process and discusses the main challenges and differences in the current photo(electro)catalytic nitrogen fixation systems. It focuses on promoting the adsorption and activation of N2 and the resolution and diffusion of NH3 generated. In recent years, reviews of the modification strategies of semiconductor materials in light of the typical cases of nitrogen fixation have been reported in the literature. Finally, the future development trend of this field is analyzed and prospected.

“…The textile, paper, and leather industries use nearly a thousand natural and synthetic organic dyes to color their products, and discharge the waste into water sources [ 1 ]. Waste discharged to water sources has been shown to contain many types of hazardous materials including, pharmaceuticals [ 2 , 3 , 4 ], dioxins [ 5 ], pesticides [ 6 ], herbicides [ 7 ], phenols [ 8 ], microorganisms [ 9 , 10 , 11 , 12 ], and textile dyes [ 13 , 14 , 15 ]. Therefore, water pollution has become a global problem that severely restricts the sustainable development of human society.…”

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.

A new study has successfully fabricated a CuO/CuSe heterojunction nanocomposite using an eco-friendly green method, which can be used as a potential photocatalyst and for phenol sensing applications. The nanocomposite has been characterized using various microscopic and spectroscopic methods, and it was found to have a direct band gap value of 2.14 eV, which indicates it can exploit visible light for its properties. The nanocomposite was tested for photocatalytic degradation of two dyes, Rhodamine B (RhB) and Methyl Orange (MO), and achieved removal efficiencies of 99.32 % and 88.20 %, respectively, using hydrogen peroxide. The nanocomposite was also found to have potentiality for practical use in phenol sensing, detecting concentrations of 0.2-1.4 μM phenol in solution and demonstrating 96-100 % phenol recovery in real water samples.
