Summary: This study investigates the effect of alkali metal salt promoter K2CO3 on the cyclic performance of CaO-based sorbents. It is found that low concentrations of K2CO3 significantly improve the cyclic performance of CaO, while high concentrations reduce the CO2 uptake performance. The stability of K2CO3 is influenced by the gas environment, with partial volatilization at high temperatures leading to a decrease in K content in the samples.

Summary: Highly efficient and stable Zr-incorporated CaO-based sorbents were synthesized using a cigarette butt-assisted combustion synthesis (CAC) method. The CAC method showed superior cyclic CO2 capture capability and shorter synthesis time compared to wet-mixing and sol-gel methods. The optimal combustion temperature for synthesizing Zr-incorporated CaO-based sorbents using CAC method was found to be 750 degrees C. Synthetic sorbents with 25 wt% ZrO2 exhibited outstanding CO2 capture performance due to the generation of extensive CaZrO3 grains. The combination of cigarette butt-assisted combustion and graphite-moulding enabled the preparation of practical Zr-incorporated CaO-based pellets.

Summary: Amine grafting under hydrous conditions using hierarchical bimodal mesoporous silica has shown promising results in developing adsorbents with high amine loading and superior CO2 capture performance. The diffusional properties of the hierarchical bimodal silica supports contribute to greater amine dispersion and utilization, resulting in significantly higher CO2 adsorption capacity and amine efficiency compared to traditional SBA-15 type adsorbents. Wet grafted hierarchical bimodal silica demonstrated excellent cyclic stability and breakthrough capacity, making it a promising candidate for CO2 capture from ambient air and industrial gas streams.

Summary: Understanding the effects of different structural parameters of CaO-based CO2 sorbents on cyclic CO2 uptake is crucial for their advancement. Through mechanochemical activation, CaO-based sorbents with varying ratios of Na2CO3:CaCO3 were synthesized to investigate the impact of sodium species on the sorbents' structure, morphology, carbonation rate, and cyclic CO2 uptake. The addition of Na2CO3 in the range of 0.1-0.2 mol% significantly improved CO2 uptake by up to 80% after 10 cycles compared to untreated CaCO3, while higher Na2CO3 loadings (>0.3 mol%) led to a decrease of more than 40% in cyclic CO2 uptake due to accelerated deactivation caused by sintering and the presence of crystalline Na2Ca(CO3)(2) species with high mobility of Na.

Summary: Nanocrystalline ZnO sponges doped with EuO1.5 were successfully prepared by heating metal-salt complex based precursor pastes. Phase separation between ZnO and c-Eu2O3 was observed at temperatures above 700 degrees C. The clean oxide made at 600 degrees C showed a slight volume increase compared to undoped ZnO, and the Eu-doping had little effect on the local structure of ZnO.

Summary: In this study, we demonstrate a bottom-up evolution route to prepare ultrafine Rh nanoparticles with large lattice spacings and grain boundaries by electrochemically reducing Cs3Rh2I9 halide-perovskite clusters on N-doped carbon. These Rh nanoparticles derived from Cs3Rh2I9 clusters exhibit significantly enhanced mass and area activity toward hydrogen evolution reaction in both alkaline and chloralkali electrolyte, surpassing liquid-reduced Rh nanoparticles and bulk Cs3Rh2I9-derived Rh via top-down electro-reduction transformation. Theoretical calculations reveal that water activation could be promoted on Cs3Rh2I9 clusters-derived Rh nanoparticles enriched with multiply sites, thereby facilitating alkaline hydrogen evolution.

Summary: A photocatalyst TiO2/Ti-BPDC-Pt with a self-grown TiO2/Ti-MOF heterojunction, selectively anchored high-density Pt single-atomic cocatalysts on Ti-BPDC, achieves photocatalytic hydrogen evolution. The intimate heterojunction efficiently separates electrons and holes in a direct Z-scheme, and Pt is selectively anchored on Ti-BPDC in the form of single atoms. The tailored TiO2/Ti-BPDC-Pt exhibits significantly enhanced activity compared to other TiO2- or MOF-based catalysts, showing the importance of the balance of two simultaneously exposed domains of heterojunctions.

Summary: The use of machine learning to predict the performance of specific adsorbents in phosphate adsorption shows great promise in saving time and revealing underlying mechanisms. However, the small size of the dataset and insufficient detailed information limits the model training process and the accuracy of results. To address this, the study employs a fuzzing strategy that replaces detailed numeric information with descriptive text messages on the physiochemical properties of adsorbents. This strategy allows the recovery of discarded samples with limited information, leading to accurate prediction of adsorption amount, capacity, and kinetics. The study also finds that phosphate uptake by adsorbents is generally through physisorption, with some involvement of chemisorption. The framework established in this study provides a practical approach for quickly predicting phosphate adsorption performance in urgent scenarios, using easily accessible information.
