In this study, Co_xZn₁⁻_xO (X = 0, 0.06, 0.18, 0.36, 0.54, and 1) nanoparticles were synthesized by one‐step solution combustion synthesis method. The critical role of X values and fuel (glycine)‐to‐oxidizer (F/O) ratios (0.75, 1, and 1.25) were investigated on the physicochemical properties of synthesized particles. X‐ray diffraction (XRD) results showed that by increasing the X molar fraction, up to 0.36 mol. %, at the F/O ratios of 0.75, 1, and 1.25, crystallite size decreases from 31 to 26, 39 to 31, and 64 to 43 nm, respectively. ZnO‐Co₃O₄ mixed oxide nanopowders were directly crystallized at X = 0.54 in all F/O ratios. Semi‐quantification evaluations of XRD results showed that the F/O ratio had a direct effect on the quantities of the crystallized and the content of the amorphous phases. According to the vibrating sample magnetometer analysis results (VSM), the greatest magnetization saturation (M_s) value of 30 emu/g was obtained at X = 1 and F/O ratio of 1.25. Calorimetry analysis revealed that by increasing the content of the doping agent, ie, cobalt ion, up to the molar fraction of 0.18, dark green color is observed in the specimens, and the deepest green color was obtained at F/O = 1.

硝酸甘氨酸比对CoxZn1-xO纳米粒子理化性质的重要作用

在这项研究中，Co _x Zn ₁ ^- _x O（X = 0、0.06、0.18、0.36、0.54和1）纳米粒子通过一步固溶燃烧合成方法合成。X值和燃料（甘氨酸）与氧化剂（F / O）之比（0.75、1和1.25）对合成颗粒的理化性质的关键作用进行了研究。X射线衍射（XRD）结果表明，通过增加X摩尔分数，可以达到0.36 mol。F / O比为0.75、1和1.25时，微晶尺寸分别从31 nm减小到26 nm，39 nm减小到31 nm，64 nm减小到43 nm。ZnO-Co ₃ O ₄在所有F / O比下，混合氧化物纳米粉体都在X = 0.54处直接结晶。XRD结果的半定量评估表明，F / O比对结晶量和非晶相含量具有直接影响。根据振动样品磁力计分析结果（VSM），在X = 1和F / O比为1.25时，最大磁化饱和度（M _s）值为30 emu / g。量热分析表明，通过增加掺杂剂即钴离子的含量直至摩尔分数为0.18，在样品中观察到深绿色，并且在F / O = 1时获得最深的绿色。
