However, the effective combination of functional evaporator backbones and solar absorbers for SVG enhancement remains challenging in high-salinity brines (≥ 10 wt%). Herein, a biomass-based polyzwitterionic hydrogel (PZH) was developed to improve the SVG performances in 10 wt% brine. Zwitterions with specific anti-polyelectrolyte effects served as backbones for accelerating H<sub>2</sub>O transportation, with fewer salt deposits and macropore channels. The biomass of straw prepared at a pyrolysis temperature at 600 ℃ was the most effective solar absorber. The synthesis of So600-PZH-8mm yielded the optimal solar evaporator with a low evaporation enthalpy of 877.79 J·g<sup>−1</sup>, a remarkable solar-to-vapor energy efficiency of 87.1%, and a high evaporation rate of 3.57 kg·m<sup>−2</sup>·h<sup>−1</sup> under 1 sun irradiation and a relative humidity of 30%. Multi-cycle evaporation tests further verified the high quality of the steam water, high salt resistance, reliability, and durability of So600-PZH-8mm in practical applications. Furthermore, density functional theory (DFT) calculations of the binding energies of charged groups and ions verified the anti-polyelectrolyte effect and swelling behavior of the PZHs. Overall, this study demonstrated the effectiveness of waste biomass as solar absorber for high-efficiency solar adsorption and water activation, which opens a new perspective to inspire the up-conversion of waste biomass in more valuable and meaningful ways.</div></div>","PeriodicalId":100595,"journal":{"name":"Green Carbon","volume":"3 1","pages":"Pages 50-62"},"PeriodicalIF":0.0,"publicationDate":"2024-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143724856","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, low-bandgap inorganic perovskites are promising materials options for the development of both single-junction and tandem solar cells. In this review, we summarize the recent studies addressing the major issues related to these perovskites, including the low phase stability and uncontrolled Sn-related defects. We also present a perspective discussion on future research directions related to these perovskites. We propose to gain insights into those unique thermodynamic and kinetic behaviors of these perovskites to understand and overcome their low phase stability. In particular, we envision that fundamental investigations leveraging <sup>119</sup>Sn NMR may open a new pathway for understanding and alleviating Sn-related defects.

In this study, we developed a method for controlling the sintering temperature and introducing H<sub>2</sub>O<sub>2</sub> post-treatment to modulate the N-doping of C catalysts, enhancing the interaction between the substrate and electrode to cause a radical reaction, thereby promoting electrocatalytic decarboxylation. When 10 g of feedstock was used, the electrocatalytic system exhibited 9.4- and 4.2-fold increases in productivity and current efficiency, respectively, compared with the conventional method. A systematic investigation combining experiments and theoretical calculations revealed that pyridine N-oxide units not only promote bridging adsorption of the substrate and the formation of a substrate-enriched electric layer but also the transfer of mass and electrons, generating more reactive carboxyl radicals. The electrocatalytic system delivers a current efficiency of 98%, which is exceptional compared to previously reported electrocatalysts. The system is in line with the development trend of the green chemical industry, combining flow reactors and photovoltaic technology. This study offers valuable insights and guidance for advancing electrocatalytic organic synthesis for future industrial applications.</div></div>","PeriodicalId":100595,"journal":{"name":"Green Carbon","volume":"2 3","pages":"Pages 291-299"},"PeriodicalIF":0.0,"publicationDate":"2024-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142357811","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
