“…If necessary, 2-3 drops of mercury metal was added into the pen holder from the top position to insure easy electrical contact between the graphite electrode and the copper wire. The electrode was allowed to dry current air in a hood for 2 hours and finally conditioned for at least an hour before use [15][16] .…”

This research was conducted to study the influence of the addition of kersen leaf extract, to understand the variation of temperature effect, and to determine the optimum result of hydrogen production in the process of water electrolysis within the kersen leaf extract using voltammetry method. The use of voltammetry cyclic method in water electrolysis was performed by setting the sweeping rate 50 mV/s. NaHCO 3 solution is functioned as electrolyte solution with a concentration of 5 g/L. A media modification which is a kersen leaf extract was added with concentration variety of 0; 0,2; 0,04; 0,008; 0,0016; 0,00032; and 0,000064 g/ml in temperature variety from 25°C, 35°C, and 45°C. The addition of media can increase hydrogen gas production. Hydrogen gas is produced higher at 45°C than it is at 25°C and 35°C. An optimum condition is obtained from sample 4 with 0,008 g/ml concentration.

“…As a result hydotalcite with ideal formula, Mg 6 Al 2 (OH) 16 CO 3 .4H 2 O is obtained. Even though hydrotalcite and hydrotalcite like minerals are found in nature, it is relatively simpler and cheaper to prepare these compounds on a laboratory scale [1][2][3][4] . …”

Previous Studies on MgO doped by alkali cations have shown that solid catalyst are efficient for the aldolization, because of having preferably a high concentration of surface basic hydroxyl groups. Indeed the Mg-Al hydrotalcites actuvated by calcinations at temperatures not exceeding 1073K are mixed oxides of Mg(Al)O type. They show the structure of MgO with smaller crystallographic parameters, then in periclase (MgO). The decrease of the size of the unit cell with increasing Al content can be accounted for by the smaller ionic size of Al 3+ (0.050 nm), then Mg 2+ (0.060 nm). These mixed oxides contain both basic sites identified to O 2-and OH -in amounts depending upon the calcinations temperature, i.e., is of the dehydroxylation degree of the hydrotalcite and Lewis acid sites provided by Al 3+ and Mg 2 . The existence of acid-base pairs justifies the catalytic properties of hydrotalcites for the Aldolisation. The synthesized Hydrotalcites were then characterized using XRD and TGA/DTA techniques, which confirmed that the synthesized materials are hydrotalcite like compounds. There after the synthesized Hydrotalcites were successfully applied for the typical Aldol Condensation reaction of propionaldehyde and formaldehyde to get desired product methacrolein. We tested catalytic activity of synthesized hyrotalcites and from the results it was clear that, the Mg -Al hydrotalcite catalyzed Aldol reaction propionaldehyde coversion of 57.78% and with selectivity 51.23% to methacrolein. Ni-Al hydrotalcite showed a propionaldehyde conversion of 53.46% with 35.46% selectivity. Co -Al XRD pattern of the formed material confirms that the material is not hydrotalcite like. This material also did not show any catalytic activity for the above said Aldol condensation reaction.
