“…These peaks correspond to the photocatalysts un-BOB/ BOC, BOB/BOC, un-BOB-480, and BOB-480 as compared with the BOC standard card (PDF#41-1488). 30,31 This indicates the successful preparation of the BOB/BOC composite catalyst. Among them, un-BOB-480 and BOB-480 did not exhibit the characteristic peak of BOB, suggesting a relatively low content of BOB with almost complete conversion into BOC.…”

In the past few decades, photocatalytic technology has made significant contributions to addressing the environmental pollution and energy crisis faced by the human society in the 21st century. The key to photocatalytic technology lies in the development of efficient photocatalysts, with the short lifetime of photogenerated charge carriers posing a major bottleneck to photocatalytic efficiency. This work presents the fabrication of a BiOBr/Bi 2 O 2 CO 3 heterojunction photocatalyst with an efficient charge transfer interface through the incorporation of surfactants and calcination treatment during the BiOBr synthesis process. The in situ construction strategy enables efficient charge transfer between BiOBr and Bi 2 O 2 CO 3 , thereby prolonging the lifetime of photogenerated carriers. By incorporating surfactants alone, the degradation rate of tetracycline by the BiOBr/Bi 2 O 2 CO 3 heterojunction photocatalyst with optimal activity is increased by over two times compared with that by BiOBr alone. Furthermore, LC−MS and quantitative structure−activity relationship analysis confirmed a significant reduction in the toxicity of intermediates generated during the photocatalytic process in the environment. Detailed analysis of the mechanism behind the enhanced photocatalytic activity is provided in this study. This research offers a novel approach for the in situ construction of heterojunction interfaces with efficient charge transfer capabilities.

“…[111][112][113] The construction of an S-type heterojunction also contributes to the enhancement of catalytic activity. 28 Under visible light irradiation for 3 h, the removal efficiency of DBP reached 73.6% using 10.0 mg L −1 Bi 2 O 2 CO 3 /Bi 2 S 3 with an S-scheme heterostructure, and the TOF was 0.0001 h −1 (Table 4) (Fig. 7), surpassing the performance of Bi 2 O 2 CO 3 (19.4%) and Bi 2 S 3 (39.4%).…”

“…Additionally, the presence of anions can also have a certain impact on degradation. An optimal amount of SO 4 2− facilitates the generation of SO 4 ˙− (eqn ( 1) and ( 2)), 28 whereas excessive SO 4 ˙− can lead to self-quenching (eqn (3)), 115 4)) or interact with active species within the system (eqn ( 5)-( 10)), thereby attenuating DBP degradation. 117 Oxygen-modified graphitic carbon nitride (O-gCN) achieved almost complete removal of 10.0 mg L −1 DBP within 2.0 h with a TOF of 0.005 h −1 under UV-vis irradiation (Table 4).…”

Recycling metals from waste materials has become a major approach to metal resource utilization, with electronic waste (e‐waste) and waste catalysts being the most important recycling resources. Although traditional recovery technologies (pyrometallurgy and hydrometallurgy) have a recovery efficiency of up to 100%, they have disadvantages of high energy consumption, high cost, and strong corrosiveness. Most importantly, they cannot achieve selective leaching. To address these issues, some fusion technologies have been developed. Electrodeposition has significant advantages in separating and purifying each metal, but if applied on a large scale in industry, it requires higher energy consumption. While photocatalytic technology has low energy consumption but low selectivity, hence further exploration is needed. Metal‐organic frameworks (MOFs) materials have great selectivity for metal ions, which are environmentally friendly and efficient, and a promising new material. Some recently typical recovery methods for six valuable metals, platinum (Pt), gold (Au), silver (Ag), lithium (Li), nickel (Ni), and cobalt (Co) in e‐waste and industrial catalysts are reviewed. The advantages and disadvantages of each method as well as their impact on the leaching efficiency and selectivity of different metals are also compared, aiming to provide useful guidance for further continuously advancing the research on efficient, selective, environmentally friendly metal recycling in the future.
