Composite structure and properties of Mn3O4/graphene oxide and Mn3O4/graphene

Novel P O codoped g-C3N4 with large specific surface area: Hydrothermal synthesis assisted by dissolution–precipitation process and their visible light activity under anoxic conditions

“…For O C 3 N 4 , in addition to adsorbed H 2 O located at 532.2 eV, one additional peak located at 530.9 eV is observed. This binding energy is probably attributed to that oxygen combines with crystal lattice carbon to form the C O bond [40]. Similar to that of O C 3 N 4 , two binding energy located at 530.8 and 532.2 eV are observed for P O C 3 N 4 .…”

Sponge-Like Porous Manganese(II,III) Oxide as a Highly Efficient Cathode Material for Rechargeable Magnesium Ion Batteries

“…RESULTS AND DISCUSSION As described in a previous study, 47 the ultrasonic treatment in the synthesis of Mn3O4 nanoparticles accelerated the formation of the Mn 2+ -ETA complex due to the alkaline properties of ETA. The complex was hydrolyzed to Mn(OH)2 when the distilled water was introduced.…”

“…47 Briefly, 12 mmol MnCl2·4H2O (2.4 g, Aldrich, 99%) and 100 mL ethanol amine (ETA, Aldrich, 99%) were loaded into a beaker, and then placed in a Branson digital sonifier (Danbury, USA). After ultrasonic processing for 10 min, 200 mL of distilled water was added into the resulting colloid solution.…”

Hybrids of NiCo 2 O 4 nanorods and nanobundles with graphene as promising electrode materials for supercapacitors

“…These encouraging characteristics provide such new materials a wide range of potential applications [11,16]. Recently, numerous works have been done on hybrid metal oxides-reduced graphite oxide (RGO), such as Mn 3 O 4 , Co 3 O 4 , NiO, Fe 2 O 3 , and NiAl-LDH [17][18][19][20][21][22]. However, spinel transition metal oxides (AB 2 O 4 ), with two metal elements provide the feasibility to tune the energy density and working voltage by varying the metal content, have less been developed [23][24][25] …”
