Influence of sodium dodecyl sulphate on the surface morphology and infrared emissivity of porous Ni film

Bubbles Templated Interconnected Porous Metallic Materials: Synthesis, Surface Modification, and their Electrocatalytic Applications for Water Splitting and Alcohols Oxidation

“…Similarly, the size of bubbles helps in the determination of pore size and the density of film depends on the pore's wall, crystalline structure, composition, and grain morphology. Several types of organic and inorganic additives including Cl − , [30] NH 4+ , [31] PEG (polyethylene glycol), butynediol(1,4), [32] bis‐3‐sodiumsulfopropyl disulfide, [33] MPSA (3‐mercapto‐1‐propane sulfonic acid), [30] sodium dodecyl sulphate (SDS), [34] Br − , [35] BTA (benzotriazole) [31a] and cetyltrimethylammonium bromide (CTAB) [36] were mixed along with electrolyte to examine their effects on metal grains morphology. The size of copper pores was also easily controlled by applying nitrogen pressure, and it was observed that an increase reduced the pore size in pressure [37] …”

Preparation of a Nickel Layer with Bell-Mouthed Macropores via the Dual-Template Method

“…Equation ( 1) can be used to express the relationship between unit adhesion energy (𝑤 ), the surface tension of the H2-liquid interface (𝛾 ), and the contact angle of the bubble on the cathode surface (𝜃 ) [15,16]. The solution with different contents of SDS is heated to 50 • C, and then the surface tension of the solution is quickly tested using a surface tensiometer (Youte Testing Instrument Manufacturing Co., Ltd., Chengde, China).…”

“…Therefore, the optimal composition of the solution is the base bath with 0.0050 g/L SDS (𝛾 = 50.2 mN/m). Equation (1) can be used to express the relationship between unit adhesion energy (w ad ), the surface tension of the H 2 -liquid interface (γ L ), and the contact angle of the bubble on the cathode surface (θ H2 ) [15,16].…”

“…The metal ion is deposited with this dynamic bubble template [8], and then, a micron-thickness metal layer with microporous and nanoramified metal walls is prepared efficiently in a few to tens of seconds [9,10]. The morphology of the deposition is greatly affected by the bubble behavior, which basically involves three basic steps, nucleation, growth, and detachment [11,12], and many factors affect the steps, such as the type and concentration of metal ions [13,14], additives [15,16], current density [5], and electrode material [17]. Generally, an effective bubble template can be produced to make the deposition porous with a sufficient proton source in solution [13].…”

“…Generally, an effective bubble template can be produced to make the deposition porous with a sufficient proton source in solution [13]. When the bubbles appear for a longer residence time [17,18], larger pores in the deposition are obtained, and smaller pores form in the deposition when the coalescence of bubbles is suppressed [15,[19][20][21]. It is worth noting that the bubbles will coalesce during the evolution process, resulting in the pore size of the deposition increasing with increasing distance from the substrate [19,22,23].…”
