“…Biochar, as a byproduct from thermal pyrolysis of biomass under an oxygen-deficient environment, could be a promising substitute for activated carbon due to its source abundance, low cost, and renewability. − In this regard, CuO is combined with biochar to construct CuO/biochar composites. Moreover, ZrO 2 addition could essentially improve the high-temperature durability of metal oxides, thus, Tang et al developed a ZrO 2 -doped CuO/biochar catalyst for mercury removal, which showed a good Hg 0 removal activity within 60–270 °C.…”

Mercury emission has become a global concern due to the potential risks Hg poses to human health and the environment. Currently, copper-based compounds, such as CuCl 2 , CuO, CuS, and CuSe, have attracted great attention in mercury emission control, because of their low cost and decent removal efficiency. This review provides an overview of the recent progress on adsorptive and catalytic oxidation removal of elemental mercury over copper-based composites. Supported CuCl 2 can majorly serve as an inexpensive and efficient catalyst toward Hg 0 oxidation. Nevertheless, the high volatility and water solubility of mercury chloride may cause halogen release and a potential leaching risk of mercury, respectively. Due to its superior redox property, CuO is fairly active in Hg 0 oxidation. Metal incorporation can distinctly strengthen the mercury removal performance. However, CuO-based composites can be easily poisoned or suppressed by flue gas constituents owing to the generation of inactive copper sulfates/nitrates or competitive adsorption. CuS-based composites appear to be the most promising sorbents for mercury capture, because of strong Hg 0 affinities and remarkable tolerances to steam and sulfur dioxide. CuSe-based composites show mercury capture performances similar to those of CuS-based composites. However, tedious synthetic processes and expensive Se precursors hinder their industrial implementation.

“…Depending on the arrangement of the carbon atoms, carbon-based materials have different morphologies. In particular, CBMs have significantly contributed toward photocatalysis because of their high surface area, outstanding conductivity, excellent chemical stability, and remarkable mechanical strength, as well as their environmental friendliness and widespread availability [ 18 ]. Considering the importance of carbon materials, their precursors must be inexpensive and effective, as well as natural and recyclable.…”

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.

Traditional energy from fossil fuels like petroleum and coal is limited and contributes to global environmental pollution and climate change. Developing sustainable and eco‐friendly energy is crucial for addressing significant challenges such as climate change, energy dilemma and achieving the long‐term development of human society. Biomass hydrogels, which are easily synthesized and modified, have diverse sources and can be designed for different applications. They are being extensively researched for their applications in artificial intelligence, flexible sensing, biomedicine, and food packaging. The article summarizes recent advances in the preparation and applications of biomass‐based photothermal conversion hydrogels, discussing the light source, photothermal agents, matrix, and preparation methods in detail. It also explores the use of these hydrogels in seawater desalination, photothermal therapy, antibacterial agents, and light‐activated materials, offering new ideas for developing sustainable, efficient, and advanced photothermal conversion biomass hydrogel materials. The article concludes with suggestions for future research, highlighting the challenges and prospects in this field and paving the way for developing of long‐lasting, efficient energy materials.
