Degradation of gas-phase o-xylene via combined non-thermal plasma and Fe doped LaMnO3 catalysts: Byproduct control

Graphene Oxide-BiOCl Nanoparticle Composites as Catalysts for Oxidation of Volatile Organic Compounds in Nonthermal Plasmas

“…On the basis of the above exploration, a possible synergetic mechanism for NTP–catalysts driven oxidation of acetone is proposed in Figure e. While gaseous acetone was introduced into the discharge region, the CO (7.58 eV), CC (3.46 eV), and CH (4.31 eV) bonds would be broken by high-energy electrons (0–10 eV) and the active specious (·O, ·O 2 – , O 3 ) derived from the effective collision between energetic electrons and molecular oxygen would further mineralize acetone, resulting in CO 2 and H 2 O . Moreover, the catalysts could also be excited by the high-energy electrons offered by the NTP reactor, and then, the excited electrons may transform from the VB of BiOCl to its CB, with h + left on the VB.…”

The h + could be a strong oxidant to decompose acetone directly or react with H 2 O to produce •OH to react with acetone.…”

Synthesis and Characterizations of LaMnO3 Perovskite Powders Using Sol-Gel Method 

“…As we elaborately explained in our former study [38], the acidic and basic features of the prepared solution reasonably give paramount hints for hydrolysis and condensation processes. Taking into consideration of the pH values in the solution phase, it is well reckoned that strong acidic pH (2-3) values entail slow gelation, which is ideal for the formation of an expanded network, while basic pH (8)(9) values trigger swift gelation, which is optimum for the formation of smaller aggregates. Keep in mind that the desired neutral pH value of the solution is readily adjusted by putting in ammonium hydroxide (NH 4 OH) so as to acquire the intended perovskite structure, as reported in Refs.…”

“…Lanthanum-based perovskite materials possess ostensible optical [1,2], magnetic [3][4][5] and catalytic properties [6]. These materials have been extensively preferred in many areas such as catalysts [7][8][9], chemical sensors [10], solid oxide fuel cell electrodes [7], hydrogen storage [11], optoelectronic devices [12], solar cells [13], magnetic materials [14,15] by virtue of stability, different oxidation states, exible oxygen stoichiometry, power conversion e ciency and isomorphic substitution of metals in their structures [10,16]. Foremost these applications, solar energy produced from perovskite-based solar cells is one of the most up-and-coming alternative energy sources on account of its relatively high energy conversion e ciency, low production cost, low production toxicity, ease of manufacture and exibility [17].…”
