Photoelectrolytic hydrogen production using Bi2MNbO7 (M=Al, Ga) semiconductor film electrodes prepared by dip-coating

Structure, thermal stability, optoelectronic and electrophysical properties of Mg- and Na-codoped bismuth niobate pyrochlores: Experimental and theoretical study

“…Only triple compositions can be formed with the pyrochlore-type structure e.g. Bi 1.5±δ 3+ M n+ Nb 1.5±δ 5+ O 7-δ (n = 2, 3) [1,2,20,21,[3][4][5][6]10,11,15,19], Bi 2 3+ M 3+ Nb 5+ O 7-δ (M -Cr, In, Ga, Fe, Al, Sc, Sm) [7][8][9][22][23][24] or M 3+ 2 BiNb 5+ O 7 (M -In, Ga) [12]. However, the presence of M cations with ionic radii smaller than (or close to) that of Bi cations is necessary, which, in its turn, occupy not less than 25 % of the cationic sites with M atoms distributed over A 2 O' and B 2 O 6 sublattices [13,14,19,[25][26][27].…”

Triple Bonds between Bismuth and Group 13 Elements: Theoretical Designs and Characterization

“…Nevertheless, to the authors' best knowledge, neither experimental nor theoretical studies have been performed on acetylene-like compounds that feature an E 13 ≡Bi (E = B, Al, Ga, In, and Tl) triple bond. It is surprising how little is known about the stability and molecular properties of E 13 ≡Bi, considering the importance of bismuth compounds [24] that contain group 13 elements in inorganic chemistry [25][26][27][28][29][30][31][32][33][34][35] and material chemistry [36][37][38][39][40][41][42][43][44][45].…”

The History and Prospective of the AOPs for Environmental Applications in Colombia**

“…Electrochemical : This is one of the AOPs that has been studied by most research groups in Colombia for the treatment of emerging pollutants. It has been coupled with other treatment systems such as photocatalysis, photo‐Fenton, ultrasound and coagulation [65–74] . The groups GIRAB and GDECON (Universidad de Antioquia) [75–82] have contributed in studies about the treatment of contaminants with different electrodes and combination with other AOPs, achieving TOC removals of 100 %.…”
