“…In that case, the typical Bi−O is one of the main index to recognize the synthesized BiOCl. From the figure, there are four dominant vibration bands at 512 cm −1 , 1300–1650 cm −1 , 2300 cm −1 and 3400 cm −1 observed in the Figure . The corresponding absorption peak at 512 cm −1 is related to the stretching vibration of Bi−O in BiOCl.…”

The overcommitting Rhodamine has aroused widely attention for the mainly organic pollutant in dying and pringting process, which is difficultly to remove the contaminate in totally. Thus, the BiOCl‐based semiconductors with relatively high photocatalytic properties toward water pullution were well defined. However, the limitted application of BiOCl due to the wider band gap, which can only be irradiated by UV light. In this work, we further introduced CdSe quantum dots (QDs), for the small‐size effect, specific surface area, special absorbability, designed for anchoring on BiOCl surface. A facial one‐step hydrothermal synthesis was developed for flower‐like BiOCl‐CdSe composites. The photodegradation of 20 mg/L RhB research under UV‐vis irradiation, 10 wt% CdSe‐BiOCl semiconductors displayed well photocatalytic abilities. From the electrochemical analysis, the effective separation of e− and h+ occured on the CdSe‐BiOCl composites. And the main work radicals during the photocatalytic produre were the e+, h+ and •O2− by the ESR analysis. The CdSe‐BiOCl composites have an immense prospective as the photocatalysts in pratical application.

“…40 The peak at 2400 cm −1 can be assigned as one feature signal of (BiO) 2 CO 3 (the green circle). 41,42 The feature peaks both existed in the (BiO) 2 CO 3 and used-BiOCl(BiOCl-formiclight) which revealed that the surface was carbonated. The generated-CO 2 adsorbed onto the surface of BiOCl thus covered the active site then reacted with BiOCl to generate (BiO) 2 CO 3 .…”

Hydrogen peroxide (H 2 O 2 ) is a superb, clean, and versatile reagent. However, large-scale production of H 2 O 2 is manufactured through nongreen methods that motivate people to develop more efficient and green technologies as alternatives. As a novel and green technology used for H 2 O 2 generation, the efficiency of photocatalysis is still far from satisfactory. Here, we demonstrate a novel and efficient path of the generation of H 2 O 2 in BiOCl photocatalysis but not the direct electron reduction of O 2 or hole oxidation of OH − to H 2 O 2 . Super high production (685 μmol/h) of H 2 O 2 by the addition of HCOOH as the hole shuttle was realized over BiOCl nanoplates. In this photocatalytic system, the BiOCl supplied abundant photoinduced holes to initiate HCOO • radical. The HCOO • further reacts with OH − to •OH which is proven to be the source of the H 2 O 2 . Apart from HCOOH, O 2 also played important roles. The O 2 not only promoted the reaction through the cycle between Bi 3+ and Bi, which decreased the combination of carriers, but also avoided the carbonation of surfaces, thus achieving the high production of H 2 O 2 (1020 μmol/h). In this work, we shed light on a deep understanding of the photocatalytic evolution of H 2 O 2 in a novel perspective and achieve high production.
