In this work, cellulose acetate polymer (CA) sheet and 2% ZnAl grafted on activated carbon grown in the form of layered double hydroxide (ZnAl/C-LDH) incorporated into CA polymer (CA-ZA2) 5 wt% (CA-ZA5) and 10 wt% of ZnAl/C-LDH (CA-ZA10) sheets were synthesized by simple casting method. All the stated sheets were fabricated with zero-valent Ni nanoparticles by adsorption of Ni⁺² ions followed by subsequent reduction with NaBH₄ and named as CA@Ni, CA-ZA2@Ni, CA-ZA5@Ni, and CA-ZA10@Ni NPs. The synthesized Ni NPs were investigated through FESEM, FTIR, XRD and EDS techniques. These supported and stabilized Ni NPs were largely used for the reduction of 4-nitrophenol (PNP), and 2-nitrophenol (ONP) in the presence of NaBH₄ which act as a reducing agent. Similarly, the catalytic efficiency was also assessed against the removal of dyes. The linear relationship and K_app were obtained from pseudo-first-order kinetics. The rate constant K_app of CA@Ni NPs for the reduction of PNP is 1.5 × 10⁻¹ and CA-ZA2@Ni (K_app = 2.6 × 10⁻¹), CA-ZA5@Ni (K_app = 3.2 × 10⁻¹), and CA-ZA10@Ni is 5.7 × 10⁻¹ min⁻¹. The highest rate constant for PNP reduction was observed with CA-ZA10@Ni NPs. The rate of CR removal with ZA10@Ni NPs is 2.05 × 10⁻¹ while the adjacent R² is 0.9013. Similarly, the rate constant and adjacent R² values were calculated for the degradation of other dyes and nitrophenols.

在这项工作中，醋酸纤维素聚合物（CA）片材和2％ZnAl接枝在活性炭上，并以5 wt％（CA-ZA5）的CA聚合物（CA-ZA2）的层状双氢氧化物（ZnAl / C-LDH）的形式生长）和10 wt％的ZnAl / C-LDH（CA-ZA10）片材通过简单的铸造方法合成。所有所述薄板都是通过吸附Ni ⁺²离子，然后用NaBH ₄还原，用零价Ni纳米颗粒制成的，分别命名为CA @ Ni，CA-ZA2 @ Ni，CA-ZA5 @ Ni和CA-ZA10 @。 Ni NP。通过FESEM，FTIR，XRD和EDS技术研究了合成的Ni NP。在NaBH ₄存在下，这些负载且稳定的Ni NP被大量用于还原4-硝基苯酚（PNP）和2-硝基苯酚（ONP）。充当还原剂。类似地，还针对去除染料评估了催化效率。线性关系和K _app是从拟一级动力学获得的。CA @ Ni NPs降低PNP的速率常数K _app为1.5×10 ^-1，CA-ZA2 @ Ni（K _app = 2.6×10 ^-1），CA-ZA5 @ Ni（K _app = 3.2×10 ^-1），并且CA-ZA10 @ Ni为5.7×10 ^-1 min ^-1。用CA-ZA10 @ Ni NP观察到PNP还原的最高速率常数。ZA10 @ Ni NP的CR去除率为2.05×10 ^-1，而相邻的R²为0.9013。类似地，计算速率常数和相邻的R ²值，以降解其他染料和硝基酚。
