“…Moreover, samples can be heated without melting and ores such as sulphide ore (if present) can be transformed into oxides and will escape as a gas. Solid state reaction route synthesis techniques are usually less expensive and appropriate for enormous productions 20 . Solid state reaction route can achieve the reduction of a compound, which cannot be occur in the presence of water i.e.…”

Manganese ferrite spinel has been synthesized by using low grade manganese ore and ferric oxide as sources of manganese oxide and iron oxide through solid state reaction route by taking manganese and iron mole ratio of 1:2 respectively. The impact of sintering temperature on phase composition and particle size is investigated. Similarly, the impact of frequency on dielectric constant, dielectric loss, AC (alternating current) conductivity and tangent losses is also investigated. The results shows the presence of spinel structure manganese ferrite (MnFe2O4) as the major phase for the sample sintered at 1200 °C. It has been established that the crystallite size increase with rise in sintering temperature. The surface morphology of the sample sintered at 1200 °C show pyramidal and triangular shape grains. The dielectric constant (εʹ) and dielectric losses (εʹʹ) were observed to decrease with increasing the sintering temperature and frequency. Furthermore, the AC (alternating current) conductivity was found to rise with rise in applied frequency. On the other hand, the tangent losses falls considerably with rise in applied frequency.

“…Mechanical activation treatment was proposed by Chen et al (Chen and Chadderton, 2004) when they reported the synthesis of aligned CNTs from iron phthalocyanine pyrolysis after ball milling treatment. Milling time was observed to be the most important controlling parameter in this process (Chen and Yu, 2005;Onishchenko et al, 2012;Onishchenko et al, 2013a). Onishchenko et al (Onishchenko et al, 2013b) reported the formation of CNTs from sphagnum moss and agricultural wastes via a mechanical activation process.…”

Biomass derived electrocatalysts with rationally designed activity, selectivity, and stability present a major sustainable approach for the electrochemical production of fuels and value-added chemicals. This review presents recent advances in the field of biomass-derived electrocatalytic nanostructures for the hydrogen evolution reaction (HER) and the oxygen reduction and evolution reactions (oxygen reduction reaction and oxygen evolution reaction), that are subject of major research efforts, as well as public and private investment, as they will play a crucial role in the energy transition and in achieving net zero carbon emissions. The review summarises experimental and theoretical investigations aiming at tuning electrocatalytic performances of sustainable C-based nanostructured materials, and present opportunities for future commercialization of innovative energy materials and applications. In reviewing relevant literature in the field, we focus on the correlation between electrocatalytic activity/selectivity and synthesis methods, composition, physical chemical characteristics, in the attempt to uncover a clear structure-activity relationship. Furthermore, this study provides a critical comparison of the different electrocatalysts in light of their catalytic mechanisms, limiting phenomena, and practical applications for sustainable future technologies.

“…Apart from the grinding time, other parameters such as atmosphere, reaction temperature could be generally neglected. It was reported that Onishchenko group has successfully produced CNTs from a large amount of natural biomass such as sphagnum moss and agricultural wastes based on this technique [123][124][125] . Differently, the biomass was first subjected to carbonize at 950 ℃ to produce amorphous carbon, followed by washing to remove mineral impurities using a mixed acid solution, then the precursors were ground in a planetary mill in many times to produce CNMs with different diameters and textural morphologies 126 .…”
