“…Bismuth‐based semiconductors are attractive photocatalysts because of their easy preparation, affordability, and nontoxicity . To the best of our knowledge, the ROS over bismuth‐based compounds are electron‐transfer products such as BiOX (X=Cl, Br, or I), except for our recent reports that the Bi atom in Bi‐based metal–organic frameworks (MOFs) displays a heavy‐metal effect and thus promotes the triplet exciton population . In this work, α‐Bi 2 O 3 with oxygen vacancies (denoted as ov‐Bi 2 O 3 ) was found to be able to produce 1 O 2 owing to chemical adsorption.…”

Oxygen vacancies are usually thought to be beneficial for photogenerated charge separation. In this work, the oxygen vacancies in ov‐Bi2O3 (Bi2O3 with oxygen vacancy) were found to be able to produce 1O2 in the dark owing to chemical adsorption. The oxygen vacancies were further found to be responsible for ov‐Bi2O3 exhibiting higher 1O2 generation under light irradiation with 1O2 as the only reactive oxygen species (ROS) than Bi2O3 with 1O2, H2O2, and others as the ROS. The photocatalytic activity was investigated for the selective photo‐oxidation of phenyl methyl sulfide to phenyl methyl sulfoxide and phenyl alcohol to benzaldehyde. In either case, ov‐Bi2O3 displayed better performance than Bi2O3, suggesting the significant role of oxygen vacancies in modulating the photocatalytic oxidation properties. This work provides an alternative approach to obtain singlet oxygen, which may guide further design of photocatalysts with high efficiency and selectivity towards photocatalytic organic synthesis.

“…MOFs, which consisted of metal ions or clusters and organic ligands, are a class of crystalline materials with large surface area to volume ratio, high porosity, adjustable pore size, tunable structures, multiple functionalities, and open metal sites [14]. Because of these excellent properties, MOFs as rapidly rising star materials have been extensively used in adsorption or separation [15], sensors [16], energy and environment [17,18], biomedicine [19,20], and so forth. In the sensing area, the unique optical and catalytic features make MOFs as optical probes, substrates or carriers, mimic enzymes for detecting pesticides [21], amino acid [22], explosive in gas phase [23], cancer biomarkers [24], small biomolecules [25,26], and so on.…”

An ultrasensitive electrochemical sensor has been constructed for the detection of single nucleotide polymorphisms (SNPs) based on DNA-functionalized Cd-MOFs-74 as cascade signal amplification probe under enzyme-free conditions. Interestingly, the introduction of an auxiliary probe did not disturb the detection of SNP targets, but could bind more Cd-MOFs-74 signal elements to enhance the different pulse voltammetry electrochemical signal 2~3 times as compared to sensing system without auxiliary probe, which obviously improves the sensitivity of the proposed sensor. Experimental results taking p53 tumor suppressor gene as SNP model demonstrated that the proposed method can be employed to sensitively and selectively detect target p53 gene fragment with a linear response ranging from 0.01 to 30 pmol/L (detection limit of 6.3 fmol/L) under enzyme-free conditions. Utilizing this strategy, the ultrasensitive SNP electrochemical sensor is a promising tool for the determination of SNPs in biomedicine.
