Band structure engineering of boron–oxygen-based materials for efficient charge separation

Abstract

The boron-based materials with indirect–direct band gaps can enhance the photo-generated electron–hole pair separation.

New potential of boron-based COFs: the biocompatible COF-1 for reactive oxygen generation and antimicrobial applications

“…34 In Fan's studies, they highlighted a number of mixed borate polar photocatalysts. 35,36 In their demonstration, the boron-oxygen units [BO 3 , BO 4 , B 2 O 5 , B 3 O 6 , etc.] were flexible in combination and could readily form easily polarized crystal structures, resulting in photoactivity.…”

Two Novel Visible‐Light‐Active Borate Composites Photocatalysts: 2 %Pt/Gd0.85Ce0.15B5O9 and 2.5 %CuO/Gd0.90Ce0.10B5O9

“…For example, the photodegradation of various dyes, B 2 O 3, [6] Bi 13 BO 20.95, [7] Bi 2 CaB 2 O 7, [8] Bi 2 ZnOB 2 O 6, [9] Cu 3 B 2 O 6, [10] YBO 3, [11] and 4ZnO • B 2 O 3 • H 2 O [12] were reported active under ultraviolet light. The photodecomposition of chlorophenol or tetracycline, K 3À x Na x B 6 O 10 Br, [13] InBO 3, [14] KBaB 5 O 9, [15] NaBaB 5 O 9, [15] Na 3 VO 2 B 6 O 11 [16] and Zn 4 B 6 O 13, [17] except SrBi 2 B 2 O 7 [18] and FeBO 3 : (C, N), [12] have only been reported for ultraviolet light illumination.…”
