The distinct role of boron doping in Sn₃O₄ microspheres for synergistic removal of phenols and Cr(vi) in simulated wastewater

Abstract

Boron doped Sn3O4 microspheres constructed from nanoplates with an unexpected synergistic effect upon simultaneous removal of phenols and Cr(vi) in simulated wastewater.

Efficient solar light-driven hydrogen generation using an Sn3O4 nanoflake/graphene nanoheterostructure

“…absorption at 490 nm. 32 This is attributed to the strong electronic interaction between graphene and Sn 3 O 4 , similar to that in TiO 2 /graphene composites. 33 The main purpose of graphene is to increase the effective charge separation so that more efficient utilization of light can be obtained.…”

“…The overall reaction is as follows. 32 4SnCl 2 + 2OH − → Sn 4 (OH) 2 Cl 6 + 2Cl − Sn 4 (OH) 2 Cl 6 + 6OH − + 6OH − + graphene → 4Sn 2+ Cl 6 + 6HCl + n H 2 O + rGO 4Sn 2+ + 6OH − + rGO → 4SnO + rGO + n H 2 O 6SnO + 2O 2 + rGO → 2Sn 3 O 4 /rGO …”

Cumulative effects of doping on Sn3O4 structure and electrode performance for rechargeable sodium-ion batteries

“…The strong peaks located at 140 and 169 cm À1 correspond to phonon modes, i.e., the stretching vibration of Sn-O bonds of triclinic Sn 3 O 4 . 30,31 A weak peak observed at 243 cm À1 also belongs to the Sn 3 O 4 phase. Significantly, boron has a small ionic radius, hence we could infer that B 3+ can be successfully inserted into the crystal lattice of Sn 3 O 4 and Sn 4+ can be replaced by B 3+ .…”

Recent advances in VOCs and CO removal via photothermal synergistic catalysis

“…Subsequently, photocatalysis arouses much attention because it does not produce secondary pollution, requires mild reaction conditions, and has low energy consumption. Using photocatalysis, CO2 reduction [19][20][21][22][23][24][25][26], water splitting [27][28][29][30][31][32][33][34][35][36][37][38][39][40], air and water purification [41][42][43][44][45][46][47][48][49][50][51], and bacterial decontamination [52][53][54][55][56] have been widely applied. In addition, the photocatalytic degradation of VOCs has become a research hot topic because of its low energy consumption for VOCs removal.…”
