Ultrafast laser dynamics of metal organic frameworks/TiO2 nano-arrays hybrid composites for energy conversion applications

Photoelectroactive metal–organic frameworks

“…MSSCs share a similar architecture to DSSCs with the substitution of dyes by MOFs as sensitizers. 274 MOFs have been applied as photoanodes, 274,275,[325][326][327] and photoactive layers 328 in MSSCs. For instance, a Zn MOF constructed from Zn(NO 3 ) 2 -$6H 2 O and mixed organic linkers of H 2 TCPP and 2,2 ′ -dimethyl-4,4 ′ -bipyridine (DMBPY) was grown on a ZnO-decorated FTO glass substrate as a photoanode in liquid-junction MSSCs, which showed a PCE of 0.86% under AM 1.5G illumination due to efficient charge separation and charge transfer besides charge injection (Fig.…”

“…The Ru MOF/TiO 2 photoanode coupled with the Pt-coated FTO counter electrode in the presence of I 3 − / I − redox electrolyte under 1 sun irradiation was reported to show a PCE of 0.42%. 327 It is worth mentioning that a Zr MOF constructed from ZrCl 4 and 3-hydroxy-2-[7-(4-carboxy-2-hydroxyphenyl)-1,3,6,8-tetraoxo-3,6,7,8-tetrahydro-1H-benzo[Imn] [3,8]phenanthrolin-2-yl] benzoic acid was coated on p-type semiconductors (Si or GaP) with TiO 2 as photocathodes for potential application in MOFbased photoelectrosynthesis, which showed the enhancement of photovoltage in the presence of the redox mediator tris(2,2 ′bipyridine)cobalt(III) tris(hexauorophosphate) under AM 1.5G illumination (Fig. 10b).…”

Surface plasmon assisted high-performance photodetectors based on hybrid TiO2@GaOxNy-Ag heterostructure

“…Compared to these methods, the atomic layer deposition (ALD) technology can achieve low temperature, precise controllability, and unique nanostructures with large area uniformity [15] . Based on nano-core-shell arrays, many promising applications, such as transistor arrays, sensor arrays, transparent electrodes, and energy harvesters, have been developed [16,17] . Therefore, high-throughput, low-cost, and large-scale preparation of one-dimensional, level-ordered, core-shell nanostructures, and high-performance photodetectors can be realised using TiO 2 nanowire arrays and plasmaenhanced atomic layer deposition (PE-ALD) to prepare GaO x N y .…”
