New Single Source Route to the Molybdenum Nitride Mo₂N

Abstract

Dispersed Mo(2)N with lamellar morphology and high specific surface area was obtained from the decomposition of the (HMT)(2)(NH(4))(4)Mo(7)O(24) salt (HMT = hexamethylentertramine) in the temperature range 550-800 degrees C. During the thermal decomposition, reduction of Mo species by carbon from the HMT ligand occurs, with release of CO gas.

Synthesis of an iron phosphide catalyst based on sulfides and hydrodesulfurization property

“…Therefore, the design and synthesis of applicable catalytic materials is the key to improve the performance of hydrodesulfurization. Over the years, scholars have developed of a wide range of the hydrodesulfurization catalysts, such as transition metal sulfides [2], carbide [3,4], nitrides [5,6], precious metals [7,8], and phosphides [1]. In particular, transition metal phosphides exhibit a catalytic ability similar to precious metals in the hydrodesulfurization reaction, and have excellent activity and sulfur resistance.…”

Exploration on synthesis of activated carbon supported molybdenum carbide, nitride and phosphide via carbothermal reduction route

“…As reported by Afanasiev [17], dispersed Mo 2 N with high specific surface area could be obtained from the decomposition of a molybdate HMT (HMT: hexamethylenetetramine) complex under argon atmosphere. Li and co-workers [18] reported that bulk and supported Co 3 Mo 3 N and Ni 2 Mo 3 N could be also obtained by the HMT route.…”

“…Recently, several papers reported that transition metals of carbides, nitrides and phosphides can be obtained from the decomposition of transition metals complexes with carbon-containing precursors under inert atmosphere [17][18][19][20][21][22][23]. As reported by Afanasiev [17], dispersed Mo 2 N with high specific surface area could be obtained from the decomposition of a molybdate HMT (HMT: hexamethylenetetramine) complex under argon atmosphere.…”

MoC x species embedded in ordered mesoporous silica framework with hierarchical structure for hydrogenation of naphthalene

“…Ar, He) instead of accumulating there to form surface carbon contaminants. Typical single-source precursors, for instance Mo VI -hexamethylenetetramine hybrids [12], Mo VI -aniline hybrids [13], and Mo VI -melamine hybrids revealed and studied in depth by our group [14], have demonstrated their applicability to synthesize single phase molybdenum carbide by simple thermal treatment.…”
