“…This behavior was observed in the literature for materials with small particle sizes (micrometers or nanometers) that form after the ball milling. 39,40 The He-based densities of the HG and BM materials were measured (Figure S4c and Table 1), and the values increased with increasing structural organization for the HG (C-HG, CP-HG, and P-HG) samples. On the other hand, the BM materials exhibited the same tendency with increasing He densities across the series, however, the values were higher than those of the hand ground materials.…”

Hard carbon (HC) and soft carbon (SC) are very attractive electrode materials for potassium-ion batteries (KIBs). However, specific attention must be devoted to electrode preparation to preserve their properties. This work reports the effects of the milling conditions (ball milling and hand grinding) used for HC and SC (or mixtures) on their properties and electrochemical performance. The properties were strongly affected by the use of ball milling instead of hand grinding. Ball milling gave a homogeneous morphology with small particles but a more disorganized structure containing inorganic impurities. A higher specific surface area, more oxygencontaining groups, and a greater active surface area were also generated. In addition, the more disorganized materials with a higher oxygen content (i.e., hard carbons) were the most influenced by ball milling. These modified properties had a negative impact on the performance. In contrast, hand grinding of the materials provided the best initial Coulombic efficiency (ICE) and greater capacity retention during cycling, i.e., 79% (HC) and 91% (SC) after 50 cycles. Post-mortem XPS studies revealed the nature of the solid electrolyte interphase (SEI) and the possible reasons for the low ICE. The SC was tested in a full cell vs C-coated KVPO 4 F 0.5 O 0.5 and delivered promising performance at high C-rates.

“…The variance of the effect size is calculated by the following equation [ 81 ]:

where, SD t , and SD c represent the standard deviation of each test variable in the experimental and control groups, respectively, and n t and n c represent the number of repetitions in the experiments of the experimental and control groups, respectively. The weighted response ratio to ( RR ++ ) is used to express the overall response effect of variable conditions such as reaction time on the experimental and control groups, which is calculated as follows [ 82 ]:

where n denotes the number of experimental groups, the weighting factor is represented by the inverse of the variance of the effect size 1/ v , i and j represent the i -th and k -th treatments, respectively, and k is the observed value in the observed group.…”

With the continuous advancement of global industrialization, a large amount of organic and inorganic pollutants have been discharged into the environment, which is essential for human survival. Consequently, the issue of water environment pollution has become increasingly severe. Photocatalytic technology is widely used to degrade water pollutants due to its strong oxidizing performance and non-polluting characteristics, and BiVO4-based photocatalysts are one of the ideal raw materials for photocatalytic reactions. However, a comprehensive global analysis of the factors influencing the photocatalytic performance of BiVO4-based photocatalysts is currently lacking. Here, we performed a meta-analysis to investigate the differences in specific surface area, kinetic constants, and the pollutant degradation performance of BiVO4-based photocatalysts under different preparation and degradation conditions. It was found that under the loading condition, all the performances of the photocatalysts can be attributed to the single BiVO4 photocatalyst. Moreover, loading could lead to an increase in the specific surface area of the material, thereby providing more adsorption sites for photocatalysis and ultimately enhancing the photocatalytic performance. Overall, the construct heterojunction and loaded nanomaterials exhibit a superior performance for BiVO4-based photocatalysts with 136.4% and 90.1% improvement, respectively. Additionally, within a certain range, the photocatalytic performance increases with the reaction time and temperature.

To boost the adsorption‐photocatalytic performances of biochar in wastewater treatment, biochar was modified with ternary metal oxides ZnO, Sm2O3, and MgO (ZnSm/Mg‐biochar) via the one‐step pyrolysis method. The optimal 2b‐ZnSm/Mg‐biochar with a Zn/Sm molar ratio of 1:1 exhibited the better removal activity of RhB in comparison with biochar, 2‐Mg/biochar, and b‐ZnSm/biochar. The removal efficiency and adsorption capacity of 2b‐ZnSm/Mg‐biochar was 99.46% and 979.22 mg g−1 for RhB solution of 410 mg g−1, respectively. The adsorption kinetics and isotherms of ZnSm/Mg‐biochar composites were as described by second‐order and Langmuir models, respectively. The abundant vacant sites at the junction interface of ZnO, Sm2O3, MgO, and biochar were favorable for the adsorption and photon capturing, achieving the efficient photo‐conversion of RhB under the stimulated solar‐light irradiation.
