Abstract

Sintesis material Na2MnPO4F/C dengan variasi jenis karbon Citric Acid dan Glukosa telah berhasil dilakukan. Kandungan karbon pada masing-masing jenis karbon sebesar 5wt%. Sintesis dilakukan dengan metode solid-state. Karakterisasi yang dilakukan dalam penelitian ini adalah uji DTA-TGA, XRD, PSA, SEM-EDX, dan FTIR. Hasil karakterisasi DTA-TGA didapatkan temperatur 350⁰C yang mengindikasi adanya pengurangan massa akibat dekomposisi bahan dan karbonisasi, dan pada 800⁰C proses pembentukan fasa. Hasil XRD didapatkan struktur monoklinik Na2MnPO4F dengan space group P21/n. Pelapisan karbon yang dilakukan menyebabkan penurunan nilai volume sel dan ukuran kristal. Hasil analisis SEM menunjukkan partikel yang tidak beraturan (irregular shape). Hasil PSA menunjukkan ukuran partikel pada NMPF 0%, NMPF 5%G, dan NMPF 5%CA masing-masing sebesar 1127, 730, dan 532 nm. Sedangkan hasil analisis FTIR didapatkan bahwa terdapat ikatan mode peregangan (stretching) Mn-O, mode tekukan (bending) asimetri O-P-O, dan mode peregangan (stretching) simetri dan asimetri P-O, serta mode peregangan (stretching) simetri C-C. Tidak adanya pengaruh pelapisan karbon pada gugus fungsi Na2MnPO4F/C yang teramati, dimana Citric Acid dan Glukosa hanya menempel secara fisis sebagai pelapis pada material komposit Na2MnPO4F/C.

The synthesis of Na2MnPO4F/C material with various types of carbon, Citric Acid and Glucose has been successfully carried out. The carbon content in each type of carbon is 5wt%. The synthesis was carried out by the solid-state method. The characterizations in this research were the DTA-TGA, XRD, PSA, SEM-EDX, and FTIR tests. The results of DTA-TGA obtained a temperature of 350⁰C which indicates a reduction in mass due to decomposition and carbonization, and at 800⁰C the phase transformation process. XRD results showed a monoclinic structure of Na2MnPO4F with a P21/n space group. Carbon coating is carried out causing a decrease in the value of cell volume and crystal size. The results of the SEM analysis showed irregular particles. PSA results showed that the particle sizes at NMPF 0%, NMPF 5%G, and NMPF 5%CA were 1127, 730, and 532 nm, respectively. While the results of the FTIR analysis show that there are Mn-O stretching modes, O-P-O asymmetry bending modes, and P-O symmetry and asymmetry stretching modes, as well as C-C symmetry stretching modes. No effect of carbon coating on the Na2MnPO4F/C functional group was observed, where Citric Acid and Glucose only physically attached as a coating on the Na2MnPO4F/C composite material.
