Mixed crystalline phases and catalytic performance of OMS-2 based nanocomposites for one-pot synthesis of quinazolines with O2 as an oxidant

Activation of O2 over three-dimensional manganese oxide nanoprisms under ambient conditions towards oxidative removal of aqueous organics

“…[60][61][62] As one of α-MnO 2 materials, OMS-2 that is composed of KMn 8 O 16 has been widely applied as a catalyst for the activation of persulfates and O 2 under harsh conditions. [63][64][65][66][67] However, examples of the synthesis of three-dimensional OMS-2 have been very limited to date. Raj's group synthesized hierarchical 3D mesoporous MnO 2 with weak α-phase using KMnO 4 and Zn powder.…”

Pd single-atom decorated OMS-2 nanorod for efficient silane oxidation

“…67.111 m 2 g −1 ), meaning that more active sites were available for the Pd-doped catalyst (Table S1, ESI†). 37 The N 2 adsorption–desorption isotherms for all samples were type IV curves with an obvious hysteresis loop of type H3 (Fig. S1, ESI†), which is characteristic of capillary condensation in mesoporous materials.…”

Manganese oxide-based catalysts for the sustainable synthesis of value-added chemicals through oxidation processes: a critical review and perspectives for the future

“…Yao et al 112 further developed PW-OMS-2 as a heterogeneous catalyst for quinoxaline synthesis (Scheme 19). The PW-OMS-2 catalyst exhibited extraordinary catalytic performance for quinoxaline synthesis, as compared to the negligible catalytic activity on α-, β-, γ-, and λ-MnO 2 catalysts.…”
