層狀雙氫氧化物 (LDH) 和/或氧化物催化劑是許多科學論文中最常研究的催化劑。然而， 隨著時間的推移，研究的新穎性和貢獻性要求已經將這些催化劑研究主題推向一些需 要“過於複雜”結構工程的“極端”角落。在這項研究中，提供了一種更“經典”和相對方便 的催化劑合成方法。將氫氣流入已經合成的氫氧化物和/或氧化物結構中，這種方法簡 稱為氫化。在這項研究中，發現空氣氣氛下的預熱處理效果是多餘的。這一點已由“空 氣煅燒”和“直接組”兩組樣本之間的微小差異證明，這兩組分別代表在空氣氣氛下有和 沒有預熱處理。研究發現，在氫析出反應（ HER） 中，在相應電位值下，以 4 小時氫 化持續時間的空氣煅燒樣本和 4 小時氫化持續時間的直接氫化樣本的電流密度達到最 高電化學性能，記錄的電位分別為 -207 mV @ -100 mA.cm-2； -120 mV @ -10 mA.cm-2 和 -195 mV @ -100 mA.cm-2； -111 mV @ -10 mA.cm-2。對於氧析出反應（ OER）， 在相 應電位值下，以原始樣品的電流密度達到最高電化學性能，記錄的電位為 1628 mV @ 100 mA.cm-2； 1516 mV @ 10 mA.cm-2。;Layered double hydroxide (LDH) and or oxide catalysts are the two most commonly studied catalysts in many scientific papers. As time progressed, however, the nature of newness and contribution-seeking of the research have pushed these catalyst study topics into some “extreme” corners which required the involvement of “overly complicated” structures engineering. In this study, a more “classic” and relatively convenient catalyst synthesis method is offered. Flowing hydrogen into an already synthesized hydroxide and or oxide structure is the definition of the method discussed, called hydrogenation in short. In this study, the effect of pre-heat treatment under an air atmosphere is found to be redundant. Proven by the insignificant differences between the two groups specimens of “air calcined” and “direct group”, which stand for with and without pre-heat treatment under an air atmosphere. It is found that The highest electrochemical performances in terms of current density achieved at the respective potential values for HER are achieved by 4 hours of hydrogenation durations for air-calcined specimens and 4 hours of hydrogenation durations of a directly hydrogenated specimen with the recorded potential of -207 mV @ -100 mA.cm-2; -120 mV @ -10 mA.cm-2 and -195 mV @ -100 mA.cm-2; -111 mV @ -10 mA.cm-2, in order. While for the OER, the highest electrochemical performance was achieved by the pristine sample in terms of current density per respective potential values, with the recorded potential of 1628 mV @ 100 mA.cm-2; 1516 mV @ 10 mA.cm-2
