“…Utilizing thermodynamic equations to fit and analyze the acquired data, the summarized thermodynamic parameters are presented in Table S5. The equation is determined according to the following formulas: 47 = °°i k j j j j j y (7) where C e (mg/L) is the remaining concentration of Br − at equilibrium. ΔS°, ΔG°, and ΔH°represent standard entropy change, Gibbs free energy of adsorption, and the heat of the adsorption, respectively.…”

Utilizing metal−organic framework (MOF) materials for the extraction of bromide ions (Br − ) from aqueous solutions, as an alternative to chlorine gas oxidation technology, holds promising potential for future applications. However, the limitations of powdered MOFs, such as low utilization efficiency, ease of aggregation in water, and challenging recovery processes, have hindered their practical application. Shaping MOF materials into application-oriented forms represents an effective but challenging approach to address these drawbacks. In this work, a novel Ag-UiO-66-(OH) 2 @delignified wood cellulose aerogel (CA) adsorbent is synthesized using an oil bath impregnation method, involving the deposition of UiO-66-(OH) 2 nanoparticles onto CA and the uniform dispersion of Ag 0 nanoparticles across its surface. CA, characterized by the intertwined cellulose nanofiber structure and a highly hydrophilic surface, serves as an ideal substrate for the uniform growth of UiO-66-(OH) 2 nanoparticles, which, in turn, spontaneously reduce Ag + to form distributed Ag 0 nanoparticles due to the abundant hydroxyl groups provided. Leveraging the well-defined biological structure of CA, which offers excellent mass transfer channels, and the highly dispersed Ag adsorption sites, Ag-UiO-(OH) 2 /CA exhibits remarkable adsorption capacity (642 mg/g Ag ) under optimized conditions. Furthermore, an integrated device is constructed by interconnecting Ag-UiO-(OH) 2 /CA adsorbents in series, affirming its potential application in the continuous recovery of Br − . This study not only presents an efficient Ag-UiO-(OH) 2 /CA adsorbent for Br − recovery but also sheds light on the extraction of other valuable elements from various liquid ores.

“…Beyond the metal-based catalysts, a catalyst of semiconducting boron carbon nitride nanosheets (SS-BCNNSs) showed a propylene yield of ∼9% with a 2.5-fold increment at 450 °C after introducing light. 70 The photogenerated electrons from SS-BCNNSs promote oxygen adsorption and reduce the energy barrier for generating active B−O• species from 1.57 to 0.88 eV (Figure 5f). The increased B−O• species under light irradiation results in a decreased reaction order of reactants and activation energy, leading to enhanced propane conversion.…”

Light olefins, crucial feedstocks in the chemical industry, are projected to reach a market size of USD 475.8 million by 2027. Traditional methods for producing light olefins, such as cracking and the Fischer–Tropsch process, are energy-intensive and heavily reliant on fossil fuels. These production methods contribute significantly to environmental issues, emitting approximately 400 million tons of CO2 annually. Integrating solar energy into the olefin synthesis process presents a promising avenue for enhancing sustainability and efficiency. Recent research reveals the potential of utilizing solar energy to activate light-alkanes and CO x , enabling solar olefin production via dehydrogenation, hydrogenation, and reduction reactions. This review overviews recent advancements and evaluates the prospects of solar energy utilization in olefin synthesis, emphasizing innovative approaches and their potential implications.
