A hierarchical graphitic carbon nitride supported by metal–organic framework and copper nanocomposite as a novel bifunctional catalyst with long-term stability for enhanced carbon dioxide photoreduction under solar light irradiation

Green, Sustainable Synthesis of γ-Fe2O3/MWCNT/Ag Nano-Composites Using the Viscum album Leaf Extract and Waste Car Tire for Removal of Sulfamethazine and Bacteria from Wastewater Streams

“…According to these images, MWCNTs are decorated with nodules of γ-Fe2O3 NPs that are homogenously tethered on their sidewalls. Such a composite structure was similarly reported in [16,21,25]. Evidently, γ-Fe2O3 or Ag NPs were uniformly spread on the MWCNTs.…”

“…As a result of this strategy, the electrical conductivity, catalysis, antimicrobial activity, and chemical stability of CNTs can be improved [19,20]. Metal NPs made of lead (Pb), silver (Ag), gold (Au), nickel (Ni), platinum (Pt), and copper (Cu) have been mainly used for the above mentioned purposes [21]. Among these types of NPs, Ag NPs have been proven to be effective in the elimination of organic and inorganic pollutants due to their excellent specific surface area [22] and outstanding antibacterial and environmentally friendly properties [23].…”

A Shish-Kebab Superstructure Film for Personal Radiative Cooling

“…With the aggravation of global warming, heat stress becomes an increasingly serious problem, which could cause physical discomfort to people, increase the risk of disease, and seriously threaten human health. , Rather than cooling the human body directly, buildings around people are cooled first in the traditional cooling process, which will inevitably generate energy waste. − Therefore, the concept of personal thermal management (PTM) has been proposed. − It focuses only on heating and cooling the human body and the local environment, thus reducing unnecessary energy consumption to the surrounding building. − In a normal environment, the body skin, which is approximately 34 °C, emits mid-infrared (MIR) radiation with a wavelength of 7 to 14 μm to the outside. This accounts for nearly 60% of the human body’s heat loss (Figure a) .…”

Gold–nickel phosphide heterostructures for efficient photocatalytic hydrogen peroxide production from real seawater

“…Artificial photosynthesis harnessing Earth-abundant resources as reaction media to produce carbon-free and high-energy chemical products provides an attractive pathway to tackle the rising concern of energy issue and carbon emission. [1][2][3][4][5][6] Among various artificial photosynthesis processes, solar-driven water splitting for H 2 production has attracted most attention. 7,8 Yet, the practical application of H 2 is challenged by its storability and transportability.…”
